摘要: 为了研究气波增压器内部气体流动,建立了气波增压器三维非定常流动模型,基于FLUENT软件进行了气波增压器气体流动的CFD(computational fluid dynamics)计算.搭建了气波增压器性能测试系统,进行了气波增压器性能试验研究并测量了CFD计算所需的边界参数.气波增压器三维非定常流动模型计算结果与试验结果一致.结果表明气波增压器运行在高转速范围时性能良好.Abstract: This research aims at investigating the flow in PWS.A 3D unsteady flow model of the PWS was completed based on the way of CFD.In order to gain the boundaries,parameters were tested by PWS test system.The PWS 3D unsteady flow model is available to simulate the flow both within the rotor and casings at different rotational speeds with good agreement with experimental results.The results give the clue that the optimum high rotor rotation speed can help the PWS gain satisfied performance.
