| 中文摘要: |
| 针对推力鳍展长变化对吊舱推进器水动力性能的影响，采用数值模拟方法研究了推力鳍展长L分别为0、30.0、44.8、60.2 mm时对吊舱推进器水动力性能、推进器各部件受力、外部绕流流场及诱导速度场的影响规律。为了验证该方法的可靠性，将数值计算结果与试验测试结果进行了对比，两者最大误差小于5%，表明计算结果可靠。此外，数值计算结果表明：推力鳍的存在可以分割螺旋桨旋转时产生的尾流，回收吊舱推进器尾部能量，且增加推力鳍展长，有利于提高吊舱推进器水动力性能，使其效率最大提高5.73%；当L=44.8 mm时，侧向力较原型吊舱推进器的降低6.1%，从而提高了船舶航行的稳定性。研究为推进器的设计提供了一定的理论基础。 |

| The effect of thrust fin span variation on the hydrodynamic performance of a podded thruster was investigated using numerical simulation. The hydrodynamic performance, forces on various components of the thruster, external flow field, and induced velocity distribution were studied for thrust fin spans L of 0, 30.0, 44.8, and 60.2 mm. To verify the reliability of the method, the numerical results were compared with experimental test data, showing a maximum error of less than 5%, indicating the accuracy of the calculations. Furthermore, the results demonstrate that the presence of thrust fins can segment the wake generated by the rotating propeller, recovering energy at the rear of the podded thruster. Adjusting the thrust fin span effectively improves the hydrodynamic performance of the podded thruster, increasing efficiency by 5.73%. When L=44.8 mm, the lateral force decreased by 6.1% compared to the prototype podded thruster, thereby enhancing the vessel's navigational stability. This study provides a theoretical basis for the design of thrusters. |
