Abstract

In present paper, the comparison of turbulent models for 2D-channel (backward step channel and fence-on-wall case) has been done. The comparison of numerical results were provided with ANSYS CFX and FastestSD. The following turbulent models have been used: k-Z, k-(u, SST, 00 -RSM, EARSM and Low-Re EARSM. As example of industrial application the thermodynamical processes in nozzle of jet engine were modeled. The practical recommendation for decreasing heat flux to nozzle wall is given.
