| 摘 要： | INTRODUCTIONWith the development of computer,consid-erable process has been made in the developmentof numerical methods for the solution of Navier-Stokes equations.However,most of these me-thods are impractical for complicated flows in adesign environment.The primary reason is thatwe can′t generate a suitable mesh easily for acomplicated configuration.Although there aremany techniques,such as structured grid or un-structured grid,which have been successfullyused for numerical simulation…

| Abstract: | Hybrid grids are used for the solution of 3D turbulence Navier-Stokes equations. The prismatic grids are generated near the wall, and the tetrahedron grids are generated in the other field. A Navier-Stokes solver using ic Baldwin-Lomax turbulence model is adopted. The numerical tests show that the above method is very efficient.`` |
