Working fluid (mixtures of inert gases) of closed gas turbine installations is described and it is shown that the thermophysical and transport properties of mixtures nonlinearly depend on their composition. The physical principle of the occurrence of gas-dynamic temperature stratification arising near obstacles in the flow of a compressible gas is described. A scheme of a closed gas turbine installation with a device for gas-dynamic temperature stratification is presented, and it is shown that it can have higher efficiency and lower heater power than a closed gas turbine installation of the classical scheme.
