| 摘 要： | 在风洞中采用多通道压力扫描阀对标准SAE汽车简化模型表面进行压力测量,并据此算得车身表面的压力系数。同时进行了对应的数值模拟。数据处理与对比的结果表明,车身上表面压力系数的模拟结果与实测数据非常接近;但在车身底部,两者存在差别,,特别是周围气流有分离的区域,差别较大。

| Abstract: | The pressure on the surface of standard SAE simplified car model is measured by multi-channel pressure scanner valve in wind tunnel,and based on which the pressure coefficients on car body surface are calculated.Meanwhile a corresponding numerical simulation is performed.The results of data processing and comparison show that the simulation results of pressure coefficients on the upper surface of model are very close to test data,but on the underbody of model there are some differences between simulation re... |
