Optimization of Local Body Shape about A Minibus Based on CFD and Wind Tunnel Test

Abstract:

In the development stage of a domestic minibus styling, the detail optimization method was used to make some changes about the car body for the purpose to get much lower value of drag coefficient combined with the detailed flow field messages reflected by the CFD analysis and wind tunnel liquid display test. Also this paper discussed the local flow structure specially, as well as the different changes of drag coefficient. The study shows that detail changes of body shape based on CFD analysis and wind tunnel liquid display test can obviously reduce the drag coefficient and optimize the aerodynamic characteristic of the minibus, which provides object basis for minibus, and also have a meaningful value in engineering application in the future.
