Abstract :
The aerodynamics characteristics of sedan model were researched by simulation, the drag coefficient and the aerodynamic characteristics around model were achieved with analysis of velocity and pressure distribution. Based on results, the below transition radius of rear-view mirror, the angle of back window and trunk lid and back trunk were optimized. The drag coefficients were reduced. The conclusions provide reference for how to reduce aerodynamic drag coefficient of sedan when developing the external shape of a new sedan.
