摘要
采用升力线理论的离散马蹄涡方法．预估船舶螺旋桨和桨后自由叶轮的水动力性能，并考虑粘性和三维流动对叶剖面的零升为角、拱度和升为系数斜率的影响，通过对三个螺旋桨和一个自由叶轮的性能预报结果表明，本文的预报结果是令人满意的．
By using the discrete horseshoe vortices method,this paper predicts the hydrodynamic performance of the marine propeller and vane wheel.The effect of viscous and three dimen sional flow on the zero- lift angle,camber and lift-curve slope of the blade section are con sidered.The performance prediction of three propellers and a vane wheel shows the results are satisfactory.
