Abstract

The computation accuracy of three different turbulence models including Spalart-Allmaras model, Wilcox's k-w model and Menter's SST model in transonic flow was investigated by solving Reynolds averaged Navier-Stokes equations. The results show that the computed force and moment using SST model has the highest accuracy compared with the experiment. The predicted distribution of pressure and position of the shock wave using Spalart-Allmaras model agrees very well with those from Menter's SST model. The predicted position of the shock wave using Wilcox's k-w model is slightly backward compared with that of SST model.
