Abstract

Method of Attract-to-Merge Control of Liquid Jet-Stream Flows (AMC method) with pure fluidic beam deflecting type liquid-to-liquid amplification is disclosed wherein the innovative technology is applied for non-destructive angular deflection of high-impulse jet-stream flow Ji by an alternative and one-sided non-invasive contact-and-pull influence of the low-impulse jet-stream flow Jc inside the pneumatic interacting area, under-pressurized by entraining influence of flow Ji, and sequent aiming flow Ji to a point of utilization in an adjacent submerged hydraulic distributing area, pressurized by impacting of flow Ji, for performing the useful work, wherein the impact of flow Ji is being distributed amongst a few of hydraulic output channels in digital (bistable) or analog mode. AMC method is being realized by the novel interdependent disposition of controlling measures and techniques inside the gaseous ambient of inverse control cavities of pneumatic interacting area with the purposefully correlated techniques for arranging output channels, thrust impact and vent free flow channels, and auxiliary (“memory”) streamlined solid surfaces inside the submerged room of hydraulic distributing area, connected with pneumatic interacting area solely by the jet-stream passing channel Ch. Both side solid surfaces of channel Ch are being curve-outlined for attracting flow Jc regarding the Coanda effect and therefore directing it along the predetermined (primarily memorized) trajectory, so that attract-to-merge influence of flow Jc upon flow Ji results in non-destructive and steady-state streaming of flow Ji cocurrently with flow Jc along the said trajectory under influence of multilayer Coanda effect based on the continuity of cocurrent flows. The submerged auxiliary solid surfaces enable keeping high impulse flow Ji along properly aiming (secondary memorized) trajectory under stable action of regular single-layer Coanda effect, while directing said flow to a point of utilization. The said novel disposition is being established for enabling the basic functions either of automatic control unit or logic gate for any embodiment of AMC method, including the amplifying of weak pneumatic or hydraulic input signal (e.g. the kind of respective output signal from an integrated Microfluidic platform) into relatively powerful output hydraulic signal, which should meet the requirements to the input signal of operated hydraulically a valve-type control unit of miniaturized (or even macro scaled) pneumatic or hydraulic power drive.

Claims

1. Method of Attract-to-Merge Control of Liquid Jet-Stream Flows (AMC method) with pure fluidic beam deflecting type liquid-to-liquid amplification that provides for innovative technology of non-destructive angular deflection of high-impulse jet-stream flow Ji, running out of a hydraulic supply facilities, by alternative one-sided non-invasive contact-and-pull influence of low-impulse jet-stream flow Jc inside any of engaged control cavities of the pneumatic interacting area, under-pressurized by entraining influence of flow Ji, and sequent aiming flow Ji to a point of utilization, that is being placed in an adjacent submerged hydraulic distributing area, pressurized by impacting influence of flow Ji, for performing the useful work, wherein the impact of flow Ji is being distributed amongst a few of hydraulic output channels either in digital (bistable) or in analog modes. The high impulse of flow Ji is being kept in full initial value to the exclusion of friction losses along its free path inside the pneumatic interacting area and through the jet-stream passing channel Ch that connects the said pneumatic area with the said adjacent hydraulic distributing area.

3. Method as claimed in claim 1, wherein pneumatic interacting area is being joined with juxtaposed hydraulic distributing area solely by the quasi-submerged jet-stream passing channel Ch, which is being so geometrically outlined and axially aligned with hydraulic supply facilities as to permit the steady-state admitting of high impulse liquid jet-stream flow Ji from pneumatic interacting area into hydraulic distributing area. The said admission is being realized either along the axial non-reflected trajectory of only flow Ji or along the curved trajectory of integral stream of cocurrent flows Ji and Jc, which repeats the predetermined curvature of any side solid surface of channel Ch. There must be established the purposefully rated correlation of downstream curvature of side solid surfaces of channel Ch with running speed of continuous, short-length or drop-shaped attracting control liquid flow Jc, which alternatively streamlines, cocurrently with flow Ji, any of those solid surfaces under influence of multilayer Coanda effect. This novel technique is being applied with the aim of enabling a desired step-type or analog function dγ

/dt or dγ

/dl of an angular deflection of high impulse flow Ji, where;

γ

-angle of flow Ji deflection;

t-real time;

1-length of channel Ch. Ultimately, this desired functions dγ

/dt and dγ

/dl are being defined by the predicted function dJi/dγ

that represents the designed distribution of high impulse impact of flow Ji amongst hydraulic outputs.

4. Method as claimed in claim 1, wherein any liquid up-flow from submerged and properly pressurized hydraulic distributing area into under-pressurized control cavities of pneumatic interacting area is being prevented by locking any gap between each of free side surfaces of flow Ji and adjacent side solid surface of channel Ch with locking whirls, which exist in dynamic equilibrium within the limits of channel Ch length. The said gaps occur either aside both sides of flow Ji in its neutral non-deflected position or from one side of deflected flow Ji, while the opposite side surface runs cocurrently with flow Jc, which is being tightly attracted to the side surface of channel Ch regarding Coanda effect. The said locking whirls are being created by generating of dynamic equilibrium between two antagonistic phenomena:

first, the attempts of liquid to go upstream of free side surfaces of flow Ji from pressurized hydraulic distributing chamber inward the under-pressurized pneumatic interacting chamber, and second, an entraining influence of flow Ji that draws the said portions of liquid back downstream into hydraulic distributing chamber.

5. Method as claimed in claims 1 and 2, wherein, with the aim of angular controlling of high impulse continuous flow Ji by a non-destructing attract-to-merge influence of sufficiently low impulse control flow Jc inside the pneumatic interacting area, there are being realized the following innovative techniques:

A predominantly acute angular oncoming of at least one steady-state continuous high impact flow Ji and at least one steady-state low impact monotonous or pulse control flow Jc in each of the inverse control cavities of said pneumatic interacting area, which oncoming flows are being constrained in degrees of freedom inside the limited gas ambient of said cavities between at least two preferably plane and parallel solid surfaces.

Shaping inside each of said inverse pneumatic control cavities at lest one closed input hydraulic control channel for inletting, either continuous or short-length pulse, pressurized control liquid flow Jc. The said hydraulic control channels are being vectored so that to direct the said control liquid flows Jc to the predetermined point of their contact with flow Ji.

Arranging inside the pneumatic interacting area some aiming guides (groves, walls, etc.) and utilizing hydrophilic and hydrophobic phenomena for proper matching the liquid-to-solid couples for steady-state admitting of the pulse short-length or drop-shaped free flow Jc to the predicted point of its contact with high impulse flow Ji. The said short-length or drop-shaped control flow Jc optionally may be free flowing along an optimally inclined open solid surface to the point of contact with flow Ji either under gravitation force or under propulsive action of auxiliary control gas flows Agf that are being organized in compliance with an entraining influence of flow Ji or with any other known technique.

Arranging input facilities (open channels, throttled openings, etc.) inward each cavity of a pneumatic interacting chamber with the aim of;

a) enabling of a gas ambient for non-destructive interaction of deflected flow Ji with attracting control flow Jc;

b) utilization of entraining influence of flow Ji for forming an auxiliary under-pressurized gas control signal Aug;

c) inletting an auxiliary pressurized gas control signal Apg for carrying out either direct or inverse deflection of flow Ji regarding a contact-and-pull action of control flow Jc.

6. Method as claimed in claim 1, wherein there is being kept the steady-state streaming of flows Ji and Jc inside the pneumatic interacting area and thru the jet-stream flow passing channel Ch in the mode of solely one-side control influence upon high impulse flow Ji. The integrity and invulnerability to undulation on side free surfaces of continuous flow Ji is being enabled by applying the phenomenon of surface tension on the gas-liquid-solid interface, and sequent creation of stabilizing soakage zones along the solid-liquid interfaces of the entire free path of flow Ji thru a pneumatic interacting area;

the said stabilizing soakage zones are being formed in the result of establishing the correlation between the hydrophilic features of liquid and the rated speed of flow Ji. The stability of low impact monotonous or pulse control flow Jc is being kept either just in the same technique as for flow Ji, if flow Jc goes as constrained streaming between at least two preferably plane and parallel solid surfaces, or by applying both the surface tension phenomenon and outlined aiming guides (grooves, walls, etc.), if flow Jc runs as a free short-length or drop-shaped pulse streaming. The running stability of joined flows Ji and Jc thru the jet-stream flow passing channel Ch is being kept by arranging multilayer Coanda effect based on the phenomenon of liquid flow continuity, wherein each of the side solid surfaces of channel Ch are being alternatively streamlined by flow Jc, which in turn attracts flow Ji and directs it to the point of utilization along the trajectory that repeats the curvature of the streamlined side solid surface of channel Ch. This running stability of joined flows Ji and Jc is being enabled by establishing the rated correlation among the speed of flow Jc, which mustn'"'"'t exceed its predetermined value, the purposefully shaped curvature of each of streamlined side solid surfaces of channel Ch, hydrophilic features of liquids in both flows, and the permissible average speed gradient of joined flows Ji and Jc regarding the conditions of flow continuity and stability of boundary layer of said cocurrent flows.

8. Method as claimed in claim 1, wherein there is being realized non-destructive separation of high impulse flow Ji either from cocurrent control flow Jc, or from streamlined by those flows Ji and Jc the solid surface in the result of creation of the steady-state bulb-shaped gaseous cavity respectively either between said flows or between said flows and said streamlined solid surface, and sequent non-disturbing extending of this cavity, either downstream or upstream, until the said separation has been done. The said technique of separation is being accomplished with keeping stability of separated flows in at least two adjacent zones:

Within the limits of jet-stream flow passing channel Ch, where the bulb-shaped gaseous cavity is being created at the contact point of flows Ji and Jc and extended further downstream inward the vent liquid flows inside hydraulic distributing area. The said contact point of flows Ji and Jc is being positioned predominantly at the boundary line between pneumatic interacting area and entrance opening of channel Ch.

Inside the submerged hydraulic distributing area, where the bulb-shaped gaseous cavity is being created at predetermined point of a streamlined auxiliary solid surface and further evenly extended either downstream or upstream of separated flows, regarding the related arrangement of said streamlined solid surface and an adjacent hydraulic vent flow channel, thru which the said cavity is being directed out of the hydraulic distributing area. The point of the said cavity creation is being chosen according criteria of minimizing the flow separation force and keeping the separated flows in a steady-state mode of streaming, as before as after the said separation has been accomplished.

11. Method as claimed in claims 1 and 2, wherein, with the aim of non-destructive servo controlling the angular deflection of high impulse liquid flow Ji by an attract-to-merge influence of sufficiently low impulse liquid flow Jc, there are being applied the following innovative flow control techniques:

Programmable separation of powered flow Ji from control flow Jc or from a curved solid memory surface is being conducted for logical negation of a previous executive instruction. The said programmable separation is being accomplished either by hydraulic or by pneumatic signals, or by both simultaneously for the rated speeding up the said separation.

The pulse-width modulation of flow Ji angular deflection is being optionally realized with forming short-length control flows Jc by pulse-width sharing the closed continuous flow Jc with the auxiliary gas bulb-type cavities, which are being inserted into the said flow Jc for pulse-width interrupting of its continuity.

The step-like or pulse-width controlling of powered liquid flow Ji deflection is being optionally conducted by an attract-to-merge influence of the drop-shaped control liquid flow Jc, where auxiliary gas flows are being used in an alternate embodiment of AMC method for propulsion of said drop-shaped flow Jc along the geometrically predicted (by grooves, walls, etc.) trajectory to the predetermined point of contact with flow Ji. The said auxiliary gas flows are being organized either in positive metric, where they are being supplied thru pressurized routs, or in negative metric, where the entraining influence of powered flow Ji upon surrounding gas is being used in any known arrangement for propulsion the said drop-shaped control flow Jc.

The multi-stream cocurrent continuous control flows Jc are being used for creation of logic instruction AND, while the alternative continuous control flows Jc are being arranged so that to be vectored onto the same streamlined solid surface together with attracted flow Ji for creation of logic instruction OR. Optionally the logic instruction OR is being realized with active influence of only one input hydraulic control signal and one inverse pneumatic auxiliary control signal, where said pneumatic control signal deflects high impulse flow Ji to opposite side into its attract-to-merge status with only one control liquid flow Jc, which tightly flows over the side solid surface of stream passing channel Ch and can not reach by itself this control flow Jc for completing the contact-to-pull influence thereof without help of said auxiliary pneumatic control signal. Since the said pneumatic control signal is being applied in continuous (i.e. analog), step-like or pulse-width (i.e. digital) regimes, the corresponding similar regimes of output hydraulic signals are being realized in the respective embodiments of AMC method.

Analog or digital controlling of attract-to-merge process in the manner of stiff function is being done by purposeful correlation between the value of running speed main hydraulic control signal in the form of low impulse liquid flow Jc, which streams cocurrently with deflected high impulse liquid flow Ji over a solid surface under influence of multilayer Coanda effect, and the shape of curvature of said solid surface. Otherwise, the stiff function of digital step-type controlling of attract-to-merge process is being realized by preferably pulse-type auxiliary under-pressurized gas control signal Aug. Analog controlling of attract-to-merge process in the manner of random function is being fulfilled by purposefully analogous an auxiliary pressurized gas control signal Apg.

The said input main hydraulic and auxiliary pneumatic control signals are being utilized predominantly from the same integrated or modular Microfluidic processing platform wherein there is being realized the multifunctional amplification of main hydraulic and/or auxiliary pneumatic signals, as far as converting said signals by AMC method either alternatively or simultaneously into one appropriately powerful hydraulic signal, which is capable to operate a valve type control unit of a mini or macro scaled hydraulic or pneumatic power drive.

2. AMC method that provides for novel combination of fluid handling techniques with spatial arrangement of supplying, controlling, directing, distributing, and intake solid facilities, which are being positioned and outlined in purposeful interdependence inside adjacent through-pass rooms of:

a) under-pressurized pneumatic interacting area, where non-destructive angular deflection of high impulse liquid flow Ji is being accomplished with separate or combined programmable effecting thereupon by attract-to-merge action of low impulse hydraulic liquid flows Jc and/or by transverse pressure momentum action of auxiliary gas flows;

b) quasi-submerged jet-stream passing channel Ch, where its side solid curve-shaped surfaces are being outlined so that to enable keeping of integral stream of cocurrent flows Ji and Jc under steady influence of multilayer Coanda effect, providing the primary memory position of high impulse flow Ji;

c) pressurized submerged hydraulic distributing area, where auxiliary curve-shaped streamlined solid surfaces are being positioned so that to enable keeping of purposefully vectored direction of high impulse flow Ji in status of secondary memory position under influence of regular single layer Coanda effect, where interrelated arrangement of sharp-ended solid splitters and streamlined curve-shaped solid surfaces provides for rated distribution of impacting impulse of flow Ji among a few hydraulic output channels, and where output hydraulic channels and vent liquid flow channels are being arranged so that to enable utilization of both direct impacting of high impulse flow Ji and additional thrust impacting of vent liquid flows upon entrance openings of output hydraulic channels. The said novel combination imparts to any embodiment of AMC method the basic functions of either automatic control unit or logic gate, including the amplifying of weak pneumatic or hydraulic input signal (predominantly-the respective output signals from integrated or modular Microfluidic platform) into relatively powerful output hydraulic signal in either digital (bistable) or analog modes, which should meet the requirements to the input hydraulic signal of a valve-type control unit of miniaturized pneumatic or hydraulic drive.

7. Method as claimed in claims 2 and 6, wherein there is being organized either the direct prime position memory of joined flows Ji and Jc (active memory) in the limits of j et-stream flow passing channel Ch, or the secondary position memory of solely high impulse jet-stream flow Ji inside the submerged hydraulic distributing area (passive memory). The said direct prime position memory of joined flows Ji and Jc (active memory) is being organized either by hydraulic control schematic (only active peripheral memory), designed to be peripheral to pneumatic interacting area or to hydraulic distributing area, or by predetermined curvature of side solid surfaces of channel Ch for enabling Coanda effect thereon while one of the said solid surfaces is being streamlined by integral stream of cocurrent flows Ji and Jc (active zonal memory). The said secondary position memory of high impulse flow Ji (passive zonal memory) is being organized by the proper geometrically shaping and spatially arranging of the predetermined number of purposefully curved auxiliary solid surfaces inside the submerged hydraulic distributing area, which curved solid surfaces are being outlined for enabling Coanda effect upon flow Ji, hence keeping the latter on the trajectory to a point of utilization of said flow Ji in performing the useful work, just after the control flow Jc has been removed.

9. Method as claimed in claim 2, wherein the necessary removing of merged cocurrent flows Ji and Jc from a primary active memory surface (actually any side surface of channel Ch) is being fulfilled either by removing control flow Jc or by the step-like or pulse increasing the speed of high impulse flow Ji that will lead to Coanda effect breakage. The necessary removing of flow Ji from a secondary passive memory surface (actually an auxiliary passive memory curved surface inside the submerged hydraulic distributing area) is being optionally accomplished by the step-like or pulse increasing the speed of high impulse flow Ji up to and over its critical value regarding regular single-layer Coanda effect.

10. Method as claimed in claim 2, wherein there are being arranged at least two liquid vent flow channels inside the submerged hydraulic distributing area, which are being destined not only for removing the extra amount of liquid that hasn'"'"'t passed thru output channels, but also for creation an additional thrust impacting influence of those vent flows on the adjacent entrance openings of hydraulic output channels. Since the said liquid vent flow channels are being properly rated by hydraulic resistance and spatial angular orientation relative to the entrance openings of adjacent output channels, the thrust liquid vent flows apply their reactive impact influence, which is an additional one to the redistributed impact of high impulse flow Ji. The said proper angular orientation of the thrust liquid vent flow channels is being accomplished so, that not to induce any disturbance upon adjacent submerged flows, which are going along the curve-shaped trajectories over auxiliary solid surfaces.

12. AMC method wherein any embodiment of its fundamental features claimed herein is being destined to operate as a pure fluidic Interface Transducer (IT) between an integrated or modular microfluidic platform (MFP) and a valve-type hydraulically operated control unit (CU) of a micro/meso-mini/macro scaled pneumatic or hydraulic drive for the purpose of packaging all the said components into an entire Microfluidic Modular Assembly (MiFluMA).
