METHOD AND DEVICE FOR SEPARATION OF SUBSTANCE (VERSIONS) Russian patent published in 2000 - IPC

FIELD: heat engines; parts of heat engines requiring increase or decrease of temperature of part of flow. SUBSTANCE: substance is brought to axisymmetrical rotary and radial motion relative to axis, then molecules of substance having small paths in near-axis area and those having large paths over periphery are selected; velocity of radial motion of flow relative to axis shall meet the following relationship: , where Vr (P, T, m) is velocity of radial motion of fraction of substance having small paths relative to axis, V (T, m) is average velocity of thermal motion of molecules of substance fraction having small path; 1+1(P, T, m) is average free path and Δr(P,T,m) is average increment in radial coordinate of molecule at thermal collision. All members are arranged on rotor which is connected with unit rotating it; substance compression unit is made in form of radial compressor; flow separation chamber is profiled in end faces lengthwise; substance flow inlet nozzle has circular section made in form of cylindrical chamber forming flow with circular reflector of substance radial flow along axis of device; vortex ejectors for compression of flow are provided at outlet; these ejectors are connected with units for removal of molecules having small and large paths. EFFECT: enhanced efficiency of conversion of internal energy of compressed substance to velocity of its tangential and radial motion. 9 cl, 2 dwg
