Axial input flow development chamber
First Claim
1. A fluid handling system comprising:
- a flow development chamber having an inlet opening and a central axis through the inlet opening, the flow development chamber comprising an outer barrel and an inner barrel concentrically mounted inside the outer barrel along the central axis to define a flow space between the outer barrel and the inner barrel, the outer barrel having an inlet end, an outlet end and an interior surface;
an inlet tube located at the inlet opening of, and concentric to, the flow development chamber such that flow through the inlet tube enters the flow development chamber along the central axis of the flow development chamber; and
a deflector located adjacent the inlet opening of the flow development chamber to direct flow tangentially around the inner barrel;
wherein the inner barrel, the outer barrel and the deflector are arranged such that the deflector sets up a flow pattern in the flow space that circulates substantially all flow through the inlet opening into the flow development chamber around the inner barrel from a location adjacent the inlet opening to the outlet end of the outer barrel.

Abstract
A system for conveying fluid through a conduit that creates a strong laminar flow of the material surrounded by a boundary layer flow of the same or a different flowable material, such that long transport distances through dramatic elevation and directional changes can be achieved. Some embodiments of the system include a blower assembly, an inlet conduit, an outlet conduit and a mixing chamber, wherein the mixing chamber includes an outer barrel, an inner barrel and an accelerating chamber. Low pressure gas is supplied to the system by the blower assembly and mixed with particulate material. The gas/material mixture is transported through the mixing chamber into the accelerating chamber and through the outlet conduit. In other embodiments, the particulate material is mixed with the gas in the accelerating chamber. Other embodiments of the system include only the mixing chamber, where a flow of at least one flowable material in the form of high or low pressure gas, liquid, and/or particulates suspended within the gas or liquid enters either laterally or axially, forms boundary layer and laminar flows, and exits through the accelerating chamber.
