为研究吊舱推进器在直航和回转工况下的推进性能，通过RANS方法结合标准k-ε湍流模型对拖式与推式吊舱推进器在不同工况下的水动力性能进行对比分析.分别计算拖式与推式吊舱推进器直航与回转工况下的推力系数与转矩系数，并与试验结果进行对比以验证数值计算的准确性.直航工况推进特性曲线、回转工况的推力系数与转矩系数曲线对比结果表明，数值计算可以准确预报吊舱推进器的水动力性能.根据该模型计算了斜流工况时两种推进器的推力、转矩系数以及轴向力和侧向力系数随角度的变化规律.结果表明，本文提出的水动力模型可以准确预报不同工况下吊舱推进器的水动力性能.

In order to study the propulsion performance of podded propulsor under direct and azimuthing conditions, the hydrodynamic performance of the puller and pusher podded propulsor under different operating conditions was compared and analyzed by using the RANS method combining standard k-ε turbulence model. The thrust coefficient and torque coefficient of the puller and pusher podded propulsor under direct and azimuthing conditions were calculated and compared with the experimental results to verify the accuracy of the numerical calculation. The comparison results between the directdrive condition propulsion characteristic curve and the thrust coefficient and the torque coefficient curve of azimuthing condition indicate that the hydrodynamic performance of the podded propulsor can be accurately predicted by the numerical calculation. According to this model, the thrust and torque coefficient, and the variation law of the axial force coefficient and the lateral force coefficient of the two thrusters with angle were calculated. Results show that the proposed hydrodynamic model can accurately predict the hydrodynamic performance of the pod propulsion under different operating conditions.
