摘　　要：对一艘75 kDWT油船的裸船体阻力在采用常规桨和混合吊舱对转桨这两种情况下的水动力性能进行了CFD评估,从船-桨-舵受力、自航因子以及船后尾流场等方面进行对比,分析对转桨与船体相互干扰特性.计算结果表明,设计航速工况下,采用混合吊舱对转桨推进方式较单桨推进方式时的船后螺旋桨收到功率下降16%左右.这主要是因为对转桨的扭矩较单桨低,且对转桨推进方式下的船身效率和螺旋桨敞水效率较单桨高.Resistance of the bare hull of a 75 kDWT tanker and hydrodynamic performances of conventional and hybrid contra-rotating propeller(CRP) pod propulsion are evaluated respectively with CFD method.Interference between the propeller and the hull is analyzed from aspects of forces on the hull, propellers and rudder, self-propulsion factor, and wake behind the hull. The results show that the delivered power of hybrid CRP pod propulsion is lower than that of the single propeller about 15%, mainly because of lower torque,higher hull efficiency and higher open water efficiency of the CRP.
