Abstract: The Menter $\gamma-\mathrm{Re}_\theta$ transition model is generalized for non-SST turbulence models. The new model is coupled with Spalart–Allmaras model. A good agreement with base model simulations and experimental data is obtained. The effect of local energy supply to a boundary layer on transition region in supersonic flow is studied numerically. It is demonstrated that heat source can delay transition.

Keywords: RANS, Spalart–Allmaras, transition, Menter transition model, boundary layer control.
