Abstract
In a regenerator for a regenerative cycle machine, regenerator foil is grooved on both sides, with intersections of grooves on opposite side forming holes at which separate flows of fluid interact to induce flows ancillary to the overall direction of flow in the regenerator, thereby enhancing heat transfer to and from the material of the regenerator and improving thermodynamic performance of the gas cycle machine.
Claims6
In a regenerator comprising multiple layers of foil, an improvement comprising:
- a layer of foil containing a multiplicity of substantially continuous grooves on a first surface thereof and a multiplicity of grooves on a second surface thereof
- wherein said substantially continuous grooves on said first surface are oriented normal to the overall direction of flow in said regenerator, and
- wherein said grooves on said second surface intersect said grooves on said first surface at an angle other than 90 degrees, and
- wherein intersections of said substantially continuous grooves on said first surface and said grooves on said second surface comprise holes in said layer of foil.
