- Аннотация: A new method for separating from the flow “cold” and “hot” parts which formed in the process of energy separation in the boundary layer of a compressible gas is presented. For this purpose, a cylindrical channel with permeable wall was used, which was connected to the settling chamber with compressed air through the supersonic nozzle. With the release of air into the environment, some of the flow seeped through the permeable wall, and its stagnation temperature was less than the initial one. The remaining part of the flow at the tube’s outlet had a stagnation temperature greater than the initial one. The cooling effect was five times greater than the Joule-Thomson effect for the investigated range of pressures and temperatures. Up to a certain point, the increase in the initial pressure of the compressed air led to an increase in the temperature difference between the cold and hot flows. But after that point the temperature difference remained almost constant.
