چکیده مقاله:

In the present work, the effect of ramp temperature on flow separation pattern of a ramp with over expanded single expansion ramp has been investigated numerically. For this purpose, the Reynolds stress turbulence model (RSM) with full multigrid grid initialization (FMG) have been carried out and the results have compared with available experimental results. The results are shown obtained results by numerical simulation Coincides with high accuracy with experimental data. After validation of the numerical methods, the effect of wall temperature on flow behavior has been studied and found that rise in wall temperature increases the separation flow.
