Study of the Influence of Dissipative Effects on the Temperature Stratification in Gas Flows (Review)

We review publications devoted to various types of gasdynamic energy separation. Processes occurring in a vortex tube, ejectors with a negative ejection factor, stratification in gas flows and flows around the walls, etc., are discussed. The data and information on the methods and methodologies allowing one to carry out investigations and/or estimations of the energy separation effect are presented. Particular attention is paid to the effect of gas dynamic temperature stratification.
