摘　　要：通过数值模拟的方法,研究了某叶栅风洞喷管有横向偏差时,叶栅试验器空风洞的端壁边界层、栅前流场均匀性。得到偏差对叶栅出口流场均匀性的影响情况。By means of numerical simulation, the uniformity of the boundary layer and front flow field in the end wall and front of the cascade wind tunnel is studied when the nozzle of a cascade wind tunnel has a transverse deviation. Thus, the influence of the deviation on the flow field uniformity at the outlet of the cascade is obtained.
