摘要
文章针对汽车空调设计了一款子午加速风机.首先,采用流体分析软件Star CCM+对其进行三维数值模拟分析,并详细分析了子午加速叶轮内部流场,从而获得了风机流场中重要的流动细节及规律.然后,分析了叶片出口安装角、叶片数、叶顶间隙对风机性能的影响;最后,选取最优方案加工了一套鼓风机CNC样件进行性能测试.结果显示,仿真结果和测试结果趋势一致,风机性能满足设计要求,所用数值模拟分析方法完全可以指导风机的优化设计.
Abstract
In this paper,a highly loaded meridian acceleration fan was designed for automobile air conditioning,and the three-dimensional numerical simulation on fan was conducted with Star CCM+.The internal flow field of meridional acceleration vortex is analyzed in detail,and the important flow details and laws in the flow field of fan are then obtained.The effects of the blade outlet angles,blade number and blade tip clearance on the fan performance were investigated.Finally,the optimal scheme was selected to process a set of blower CNC samples for performance testing.The test results show that the model tes-ting results accords with the simulation results well,and the performance of fan can satisfy the design requirements.Therefore,the numerical simulation analysis can guide the optimal design of the fan.
