摘要
为了提高货车的燃油经济性,对厢式货车的气动阻力进行了研究.采用κ-ε紊流模型对增加井字型格栅前后厢式货车的外流场进行CFD数值模拟,得到两模型周围的速度场和压力场.通过分析对比,增加井字型格栅后厢式货车的气动阻力明显降低.
In order to improve the vehicle fuel economy, the aerodynamic resistance of van was studied. CFD numerical simulations of the external flow field around the van with and without the square-formed fences were performed based on the ic--e turbulence model. The aerodynamic characteristics for the two models were calculated, which include the pressure distribution and the velocity vector distribution on the surface. The comparative analysis results show that the aero- dynamic resistance of van decreases obviously after adopting the square formed fences.
