Abstract:
Modern differential turbulence models are validated by computing a separation zone generated in the supersonic flow past a compression wedge lying on a plate of finite width. The results of three- and two-dimensional computations based on the $(q-\omega)$, SST, and Spalart–Allmaras turbulence models are compared with experimental data obtained for 8$^\circ$, 25$^\circ$, and 45$^\circ$ wedges by A. A. Zheltovodov at the Institute of Theoretical and Applied Mechanics of the Siberian Branch of the Russian Academy of Sciences. An original law-of-the-wall boundary condition and modifications of the SST model intended for improving the quality of the computed separation zone are described.
Key words:
supersonic flow, boundary layer separation, compression wedge, turbulence model, validation of models.
