%X DES(detached eddy simulation) is a hybrid method combining RANS and LES to simulate fiowfields with detached eddies. The main idea is that, RANS is used near the wall and LES method is used in the other region of the field. In this paper, DES method based on M-SST was used to simulate the complicate turbulence flows on hybrid unstructured grids and the Osher scheme was used for the spatial discretisation. The computations of the flow around a missile with a lateral jet was performed by using the newly-developed codes. The obtained results demonstrate that DES method is efficient for some simulation of the separated turbulence fiowfields.
