The paper examines the validity of the SSG (Speziale, Sarkar and Gatski, (1991)) Reynolds-stress model in vortex-shedding flows by comparing the calculations with published data on vortex-shedding past a square and a circular cylinder in a free stream. Moreover, calculations are reported for the square cylinder placed at various distances from an adjacent wall. All calculations are compared with previous ones performed with different models and published elsewhere. The results show that the SSG model is able to provide reasonably good agreement with data and also to give the results which are very comparable with LRR (Launder, Reece and Rodi (1975)) Reynolds-stress model. |
