METHOD OF GAS FLOW ENERGY SEPARATION Russian patent published in 2008 - IPC F25B9/04 

FIELD: heating.

SUBSTANCE: invention is referred to thermal physics, flow dynamics, power generation and relates to gas flow energy separation by means of eddy swirling. Method of gas flow energy separation is implemented by swirling of flow regarding to longitudinal axis generating turbulence, which transmits heat from paraxial flow layers to peripheral ones and further removal of peripheral layers to hot-gas-path and paraxial layers to cold-gas-path. Peripheral layers of flow swirled in operating chamber is periodically and repeatedly cooled (heat removal) and heated (heat supply) by means of external coolers and heaters, which are located in turns on peripheral wall of operating chamber. Sequential vortexes are generated in operating chamber (Karman vortex street) by means of nozzle located on cold flow outlet nozzle with outer diameter (0.65...0.85)·D, where D - inner diameter of operating chamber. Technical result is the improvement of energy separation effectiveness due to increase of temperature difference between hot and cold gas flows and decrease of flow dynamic losses.

EFFECT: improvement of energy separation effectiveness and decrease of flow dynamic losses.
