Sinopsis

"Energy separation" is the re-distribution of the total energy (temperature) in a fluid without external work or heat. In this paper total temperature separation of a gas flow is produced by gas-dynamic method (Leontiev's tube) proposed in [1]. A compressed air is separated geometrically into two flows by a heat-conducting material. One of the flows accelerates through the speed of sound another remains subsonic. There is a heat flux between these two flows with equal initial total temperature. As the results the rise of the total temperature of the supersonic flow and reduction one of the subsonic flow at the exit of an experimental facility with various ratio of mass flow are fixed.
