摘　　要：基于计算流体动力学(CFD)对国际标模KCS斜航状态进行数值模拟,分析不同漂角下螺旋桨在纵向、横向和垂向3个方向上的力和力矩的变化规律,并探讨漂角对推力偏心矩的影响。结合SST k-ω湍流模型和滑移网格,采用RANS方法进行数值模拟。计算考虑±30°、±20°、±10°和0°漂角。结果表明:由于横向水流会改变螺旋桨桨盘面上的载荷分布,漂角对螺旋桨的横向和垂向的力和力矩有显著影响,漂角方向对螺旋桨推力偏心矩的偏移有较大影响。Based on CFD, a numerical simulation is carried out for KCS, an international standard model, to analyze the force and moment changes in longitudinal, transverse and vertical directions when the propeller has different drift angles, and the influence of drift angle on thrust eccentricity moment is discussed. The RANS method combining with SST k-turbulence model and sliding mesh is adopted to do numerical simulation. The drift angles of ±30°,±20°, ±10° and 0° are taken into account in the calculation. The results show that the drift angle has a significant influence on the horizontal and vertical force and moment of the propeller, and the drift angle has a great influence on the offset of the propeller thrust eccentricity moment, because the transverse water flow changes the load distribution on the propeller disc surface.
