基于CFD仿真对过滤器优化设计

Optimized Design for the Filter Based on CFD Simulation

应用CFD软件对过滤器内部风道进行仿真模拟。对于复杂的内部结构采用了多面体网格,保证在结构复杂处的网格质量较高。通过分析内部的速度场和压力场,优化其内部结构,对比分析得到了性能更优的过滤器风道结构。

To optimize the structure of the filter,use the CFD soft to simulate the inner flow field.To generate the high quality volume mesh,polyhedral mesh method was used.By analyzing the pressure field and velocity field of the inner flow, we propose the optimization design proposals.Compared with original flow field, the performance of optimization design proposals is better than original＇s.
