The self-propulsion test of submarines is a key technology when evaluating its performance.In this paper,the simulation and modeling of a full appendage submarine with high-skew propeller are pre sented.Particularly,the flow patterns,the thrust and torque of the propeller and the wave resistance of the submarine are obtained via three-dimensional numerical analysis.Furthermore,analysis of the hydrody namic properties of the SUBOFF bare hull as well as the appended submarine reveals high consistency be tween...
