Sinopsis

“Energy separation” is the re-distribution of the total energy (temperature) in a fluid without external work or heat. The results of an experimental investigation of the gas-dynamic method of energy separation of a supersonic air flow are presented. It is shown that in an axisymmetric supersonic channel the presence of a central body in the form of a cylindrical tube consisting of impermeable and permeable sections leads to the redistribution of the total energy of the flow. At the central body exit the mass-mean stagnation temperature of the air increases compared with its initial temperature. Also gas-dynamic method of the energy separation is investigated more particularly in a long conical supersonic channel with an outer subsonic channel. Rise of the total temperature of the supersonic flow and reduction of the total temperature of the subsonic flow with various ratio of mass flow rate are fixed.
