Abstract

In this paper, the results, mainly experimental, on the energy separation in single-phase gas flows are reviewed. Special attention is paid to the field of scientific research of the authors: the effect of energy separation in the compressible gas boundary layer and the development of the methods and devices for machine-free temperature separation of a gas flow. The experimental data obtained by the author’s group are described in detail. Among the methods of energy separation, the Leontiev tube and exploring ways to increase its efficiency, energy separation in a channel with porous permeable walls, and the Eckert–Weise effect (aerodynamic cooling) in the transverse flow of a compressible gas stream around a single and pair of side by side cylinders are considered.
