摘要
本文由计算和实验首次说明在边界层入口处施加扰动能减轻固粒对壁面的磨损，而且加入扰动的强度越大，磨损量越小。该方法比壁面加肋条具有更好的抗磨效果，且负面作用较小，结论对工程应用有指导意义。
The numerical and experimental results show that exerting disturbance in theentrance of boundary layer can reduce erosion caused by particles. The lager amplitude of distu-rbance is, the erosion amount is. It is drawn that exerting disturbance in the entranceof boundary layer is more effective for reducing erosion than adding ribs on the wall. The results given in the paper are helpful for practical usage.
