Through the comparison of calculation results of two methods in the uniform and the non-uniform inflow, it is found that the results by two methods are very close. The calculation results by two methods are compared with open water test, and the agreement is well. The two methods can both perfectly simulate the hydrodynamics performance of podded propeller, and the method of induced potential needs less program work and can save a great deal of calculation time and memory space. It is a simpler and effective method to calculate hydrodynamics performance of podded propellers and other combined propulsions.

经过用两种方法对均匀来流和非均匀来流条件下水动力性能的计算比较，发现两种方法的计算结果很接近，并与模型试验结果吻合得很好，但用诱导速度势的方法编程工作量较诱导速度方法少，而且还可节省大量的计算时间和存储空间，是一种计算吊舱推进器和其他组合推进器水动力性能相对简单而且有效的方法。

This study found that pump jet's inflow velocity affect all flow field when in shallow water; pump-jet almost avoids tangling problem;rim-driven propellers can easily clean tangled material by reversing operation or different speed, and can still operate even when ropelike material stuck with the blades.

研究结果发现：在模拟泵喷推进器出入口方面，入口流速只在浅水时对整个流场影响较大。

The effects of main parameters of the slotted nozzles and propellers upon the performance characteristics are analyzed.

根据试验结果；分析了双体导管及螺旋桨的一些主要参数对敞水性能的影响。
