Résumé

Analysis of heat transfer augmentation technique in gas dynamic energy separation process is presented. The main parameters for energy separation efficiency are temperature recovery factor and heat-transfer coefficients at supersonic channel of the device. The research considers values of adiabatic wall temperature and recovery factor influenced by 2 factors: shock wave boundary layer interaction and separated supersonic flow behind a rib. Results indicate that local boundary layer separation regions will probably intensify heat transfer in supersonic channel of gas dynamic energy separation device.
