System of Model Kinetic Equations for a Multicomponent Gas

Abstract

A mathematical model of a multicomponent gas flow based on a model kinetic equation is presented. Flows of multicomponent monatomic perfect gases are considered. The model is tested using the example of the problem of the shock wave profile for a mixture of argon and helium in various proportions. It is shown that the model provides satisfactory agreement with the experimental data.

期刊介绍： High Temperature is an international peer reviewed journal that publishes original papers and reviews written by theoretical and experimental researchers. The journal deals with properties and processes in low-temperature plasma; thermophysical properties of substances including pure materials, mixtures and alloys; the properties in the vicinity of the critical point, equations of state; phase equilibrium; heat and mass transfer phenomena, in particular, by forced and free convections; processes of boiling and condensation, radiation, and complex heat transfer; experimental methods and apparatuses; high-temperature facilities for power engineering applications, etc. The journal reflects the current trends in thermophysical research. It presents the results of present-day experimental and theoretical studies in the processes of complex heat transfer, thermal, gas dynamic processes, and processes of heat and mass transfer, as well as the latest advances in the theoretical description of the properties of high-temperature media.
