| Abstract: | Introducing the application of polyhedral mesh in CFD,the hybrid grid was applied in the polyhedral mesh to simulate the viscous effect.An efficient method was designed to create and solve the polyhedral mesh,solutions on the M6 wing and DLR-F6 wing-body-nacelle-pylon configurations are performed,results are in good agreement with experiments,and the present method has satisfactory level and efficiency,and is suitable for application to engineering problems. |
