摘　　要：为提高船舶的推进效率,采用节能附体是一种有效手段。基于计算流体动力学(Computational Fluid Dynamics,CFD)数值计算对一艘万车汽车运输船(Pure Car/Truck Carrier,PCTC)加装预旋定子后的阻力、伴流和推进进行分析。结果表明,数值计算与模型试验吻合度较好,定子能带来3%~4%的效率提高。此外,从桨叶剖面入流的角度分析定子影响螺旋桨推力扭矩的原因。Energy saving Device are often introduced for improving ship propulsion efficiency. This paper presents the numerical studies of a Pure Car/Truck Carrier （PCTC） with a pre-swirl stator, covering the resistance/propulsion and the wake. Numerical results show a good agreement with model test data. The efficiency improvement of 3%-4%can be achieved by introduction of the stator. The angle of inflow to the propeller blades is also investigated to identify effect of the stator on the thrust and torque.
