中文摘要

Driving safety and comfort have enormous relationship with the flow field surrounding vehicles. Especially, when two cars mutally overtake each other , flow field becomes complicated because the high-speed wind impinging on vehicles will cause disturbance phenomenon. This paper analyzes the flow field of two vehicles overtaking using the Computation Fluid Dynamics (CFD) method and applies dynamic grid technique to solve the unsteady 3D Navier-Stokes equation. This study used three test models for different vehicles spaces to monitor the change in flow field and to analyze related aerodynamic coefficients. The results showed that, when two vehicles spacing is very small, aerodynamic characteristic caused by the large vehicles has a very tremendous infuence on the small car. This affect the drivability and control ability of the driver in the small car.
