Fluidic buffer volume device with reduced mixedness
First Claim
1. A system, comprising:
- a fluidic buffer volume device, comprising;
an inlet defined by an inlet wall;
a plurality of nested tubes defining annular flow paths between walls of adjacent tubes, wherein a portion of the inlet wall is centrally disposed within the plurality of nested tubes in a concentric arrangement;
an outlet; and
a fluid flow path through the inlet, the plurality of nested tubes, and the outlet, wherein the fluid flow path extends from the inlet to the outlet via a tortuous path through the annular flow paths between the walls of adjacent tubes of the plurality of nested tubes in a first direction from the inlet towards the outlet and in a second direction from the outlet towards the inlet;
wherein the fluidic buffer volume device is configured to reproduce a transient event occurring upstream of the inlet in a fluid downstream of the outlet after the fluid travels along the fluid flow path, and wherein a respective radial offset between the walls of the adjacent tubes of the plurality of nested tubes decreases from an innermost pair of adjacent tubes to an outermost pair of adjacent tubes to minimize a pressure drop of the fluid within the fluidic buffer volume device.

Abstract
A system includes an inlet pipe configured to convey a fluid and a buffer volume configured to buffer the fluid. The buffer volume includes a smallest diameter tube having a smallest diameter, a first inlet end, and a first outlet end. The first inlet end is configured to receive the fluid from the inlet pipe. The buffer volume also includes an intermediate tube surrounding the smallest diameter tube having a first capped end and a second outlet end. The first capped end is positioned next to the outlet end of the smallest diameter tube. The buffer volume also includes a largest diameter tube surrounding the intermediate tube second capped end and a third outlet end. The second capped end is positioned next to the second outlet end of the intermediate tube. The system also includes an outlet pipe configured to convey the fluid from the buffer volume.

16. A method, comprising:
-
conveying a fluid through a first pipe to a first tube in a plurality of nested tubes of a fluidic buffer volume device, wherein the first tube is centrally disposed within the plurality of nested tubes in a concentric arrangement and forms an inlet into the fluidic buffer volume device, and wherein a respective radial offset between walls of adjacent tubes of the plurality of nested tubes decreases from an innermost pair of adjacent tubes to an outermost pair of adjacent tubes to minimize a pressure drop of the fluid within the fluidic buffer volume device; conveying the fluid through the first tube in a first direction to a first outlet end;
radially dispersing the fluid from the first tube to a second tube in the plurality of nested tubes, the second tube surrounding the first tube;conveying the fluid through the second tube in a second direction opposite the first direction along an annular flow path; and conveying the fluid from the fluidic buffer volume device through a second pipe. - View Dependent Claims (17, 18, 19, 20)
