摘　　要：运用计算流体力学软件Fluent对粘性流场中导管螺旋桨的流场进行了计算分析,获得了导管螺旋桨敞水状态下的水动力性能曲线。改变螺旋桨叶梢与内壁的间隙△(△=0,0.025R,0.05R),分别计算导管桨的水动力性能,计算结果表明:导管螺旋桨的叶梢与导管内壁间隙越小,导管螺旋桨的推进效率越高。By applying software Fluent, the viscous flow field of ducted propellers is calculated and analyzed, and the hydrodynamic performance curve is obtained. With different distances/k between the blade and the duct （△= 0, 0.025R, 0.05R）,the hydrodynamic performance of ducted propellers is calculated respectively. The results show that the smaller the distance between the blade and the duct is, the higher the propulsion efficiency is.
