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.
