汽车气动附件对气动力优化的数值仿真
Numerical Simulation Optimization of Aerodynamic Accessories on Vehicle Aerodynamic Forces
摘要
Abstract
For the study of influence of aerodynamic accessories on automotive aerodynamic forces, the method of computational fluid dynamics ( CFD) was used to respectively research the influence of aerodynamic drag accessories on a SUV model and aerodynamic lift accessories on a sports car. The results show that aerodynamic drag accessories can effectively reduce aerodynamic drag of the sports utility vehicle ( SUV ). Accessories attached on the upper surface have better performance than the ones attached on the bottom surface because SUV has relatively high body and large space above the ground. Side plates of the rear wing can improve the effect of the wing by preventing the air flow from escaping, and the double wings have the best performance because of the largest pressure gap.关键词
