Abstract:

In order to adapt to new modern car styling, the aerodynamic numerical simulations based on computational fluid dynamics(CFD) are applied to the process of car styling. At first it was introduced that the process of car styling in this paper. Virtual wind tunnel test is one method of the best modern ways of aerodynamic design which will be applied in the fields of aerodynamic research widely. Together with one concept car design，the details in all the process of aerodynamic numerical simulations are narrated. Applying the virtual wind tunnel test aerodynamic drag coefficient, velocity contour and pressure distribution are got. Some advices to reduce aerodynamic drag of the designed car were put forward. In one word，it is one fast, simple and effective way to design aerodynamic car shape.

Key words: aerodynamics, computational fluid dynamics, car styling, aerodynamic characteristic
