Abstract

Official abstract text for this publication.

Disclosed is a flow device including an inlet, an outlet, and a plurality of fluid flow paths hydraulically connected in parallel to the inlet and the outlet, wherein the plurality of fluid flow paths forms a first ring of fluid flow paths circumferentially arranged at a first radial distance from a centerline of the fluid flow device a second ring of fluid flow patch circumferentially arranged at a second radial distance from the centerline of the fluid flow device, each of the plurality of fluid flow paths has a first hydraulic resistance in a forward flow direction and a second hydraulic resistance in a reverse flow direction, and the second hydraulic resistance is greater than the first hydraulic resistance.

First claim

Opening claim text (preview).

The invention claimed is: 1. A flow device, comprising: an inlet; an outlet; a first fluid flow path hydraulically connected in parallel to the inlet and the outlet; a second fluid flow path hydraulically connected in parallel to the inlet and the outlet; a first loop in the first flow path directed in a reverse flow direction of the first fluid flow path; a second loop in the second flow path directed in a reverse flow direction of the second fluid flow path; and an interconnecting path directing reverse flow from the first loop into forward flow of the second flow path and against the reverse flow direction of the second loop, wherein the first fluid flow path and the second fluid flow path have a first hydraulic resistance in a forward flow direction and a second hydraulic resistance in a reverse flow direction, and the second hydraulic resistance is greater than the first hydraulic resistance. 2. The flow device of claim 1 , wherein: each of the plurality of fluid flow paths has a first pressure drop in the forward flow direction and a second pressure drop in the reverse flow direction; and the second pressure drop is greater than the first pressure drop. 3. The fluid flow device of claim 2 , wherein at least one of the plurality of fluid flow paths includes a flow path boundary wall defined by a plurality of non-straight line segments. 4. The flow device of claim 2 , wherein the at least one loop includes a loop flow path boundary wall defined by a plurality of non-radial line segments. 5. The flow device of claim 1 , wherein each of the plurality of fluid flow paths is coaxially-arranged around a flow device centerline. 6. The flow device of claim 5 , wherein a forward flow area in each of the plurality of flow paths varies as a function of a radial distance from the flow device centerline. 7. The flow device of claim 6 , wherein the forward flow area changes with a square of the radial distance from the flow device centerline. 8. A flow device, comprising: an inlet; an outlet; and a plurality of fluid flow paths hydraulically connected in parallel to the inlet and the outlet; wherein the plurality of fluid flow paths forms a first ring of fluid flow paths circumferentially arranged at a first radial distance from a centerline of the fluid flow device, a second ring of fluid flow paths circumferentially arranged at a second radial distance from the centerline of the fluid flow device, each of the plurality of fluid flow paths has a first hydraulic resistance in a forward flow direction and a second hydraulic resistance in a reverse flow direction, and the second hydraulic resistance is greater than the first hydraulic resistance; and wherein at least one of the first and second fluid flow path rings has: a first fluid flow path hydraulically connected in parallel to the inlet and the outlet; a second fluid flow path hydraulically connected in parallel to the inlet and the outlet; a first loop in the first flow path directed in a reverse flow direction of the first fluid flow path; a second loop in the second flow path directed in a reverse flow direction of the second fluid flow path; and an interconnecting path directing reverse flow from the first loop into forward flow of the second flow path and against the reverse flow direction of the second loop. 9. The flow device of claim 8 , wherein: each of the plurality of fluid flow paths has a first pressure drop in the forward flow direction and a second pressure drop in the reverse flow direction; and the second pressure drop is greater than the first pressure drop. 10. The flow device of claim 9 , wherein an outer radius of the first fluid flow path ring matches an inner radius of the second fluid flow path ring. 11. The flow device of claim 10 , wherein at least one of the first ring and the second ring is arranged in a non-circular elliptical pattern relative to the fluid flow device centerline. 12. The flow device of claim 11 , further comprising: a first plurality of azimuthal segments in the first ring; and a second plurality of azimuthal segments in the second ring. 13. The flow device of claim 8 , wherein each of the plurality of fluid flow paths is coaxially-arranged around a flow device centerline. 14. The flow device of claim 13 , wherein a forward flow area in each of the plurality of flow paths varies as a function of a radial distance from the flow device centerline. 15. The flow device of claim 14 , wherein the forward flow area changes with a square of the radial distance from the flow device centerline.
