摘要： Numerical analyses of the cold turbulent flow in model combustion chambers were made by using turbulent model. The hybrid difference scheme and SNIP method were employed. Numerical solutions for retouchmenl length and velocity distributions were obtained in the recirculating zone of the combustion chambers. The calculation results were in fairly good agreement with the reported experimental data. The work presented in this paper was a basic part of the calculation model of sudden-enlarged combustion chambers.
