The study of aerodynamic characteristics of a notchback car with rear wing at different angles of attack

Jiang Yan

Abstract

The aerodynamic characteristics of a simplified notchback car with rear wing were studied with numerical methods of moving ground boundary condition with the CFD code STAR-CD.The drag and lift coefficient of the car with rear wing at different angles of attack at two forward speeds were calculated.Compared with the test,the results of the numerical calculation were verified correctly. It was confirmed that the rear wing could improve the wake structure and so aerodynamic characteristics were enhanced.
