    Abstract
  • The numerical simulation of the high Reynolds number, massively separated flows such as flow over the circular cylinder and supersonic base flow were performed with detached-eddy simulation based on Spalart-Allmaras turbulence model. The inviscid flux was obtained with 2nd order upwind scheme and 2nd order implicit dual time method was used for accurate time marching. Detached eddy simulation presented more resolved three dimensional turbulent vortex structures compared with corresponding RANS(Reynolds-averaged Navier-Stokes) method. The resolution of main turbulent structures in wake region and prediction of mean pressure distribution show agreement with experiments.
