摘　　要：为了提高汽车冷却风扇的运行效率、降低功率消耗和减小噪声,论文首先利用坐标变换和参数改进的方法建立了改进的汽车发动机冷却风扇的三维实体模型。然后结合风扇的台架试验的研究方法,即先将实体模型导入到GAMBIT中,建立风扇的CFD仿真分析模型。然后再采用分区域和滑移网格技术相结合的方法进行网格划分。最后,利用FLUENT软件仿真分析,给出了风扇运行的性能参数以及流量和噪声的影响因素。In order to improve the operational efficiency, decrease power consumption and reduce noise of the automotive fan. Firstly, using coordinate transformation and parameters improved methods creation three-dimensional solid model of improved automotive engine cool- ing fan, Then bench test research methods combined with fan CFD simulation analysis model to establish a fan of the first solid models impor- ted into GAMBIT. And mesh using the combination of sub-regional and siliding. Finally, the simulation analysis using FLUENT software. Provide the performance parameters of the fan using, As well as the impact of traffic and noise factors.
