摘　　要：考虑将有节能效果的舵球应用于渔船,采用计算流体力学软件STAR-CCM+对39.8 m远洋围网渔船舵桨进行舵球应用数值模拟,由推进效率、螺旋桨表面的压力分布及流场对比不同直径舵球及与螺旋桨桨毂距离组合方案下螺旋桨的敞水性能差异;分析发现对于航速较高的远洋渔船采用合适的舵球可以改善螺旋桨尾部流场分布,降低其尾流旋涡的强度,提高螺旋桨推进效率,达到一定的节能效果。The energy saving effect of applying rudder ball to fishing boat was investigated.Using CFD software STAR-CCM+,numerical simulation was carried out for application of the rudder and propeller in a 39.8 m pelagic purse seine.The open water performance of propeller with different diameter rudder balls and the distance from the propeller hub was comparatively analyzed in terms of propulsion efficiency,pressure distribution and flow field on the propeller surface.It could be concluded that the appropriate rudder bulb can improve the flow field,reduce the vortex strength in propeller wake area,improve the propeller propulsion efficiency and achieve certain energy saving effect for the high speed ocean-going fishing vessel.
