| Abstract: | The CFD method is applied to study the 3-D flow around a car in this paper. The finite volume method is used to solve 3-D steady incompressible N-S equation and the computational results of a China-made passenger ear are obtained, including 3-D velocity field, 3-D pressure field and six aerodynamic coefficients. The results have good agreement with full-seale wind tunnel test. |
