Abstract

A turbulence model is suggested to consider effect of high-speed compressibility on the turbulence process. Some series of numerical computations for turbulent non-isobaric jets have been carried out with different flow models. A satisfactory compliance is achieved between obtained numerical results and experimental data. A comparison of the simulation results with these experimental data reveals how important is to take into account an influence of compressibility corrections on the intensity of turbulent mixing.
