Abstract
The paper presents numerical simulation results of the submarine resistance in submerged condition by Computational Fluid Dynamics (CFD) method. Otherwise, the influence of the mesh size on the simulation results is also mentioned. A comparison of the simulation results and the test results in the towing tank is made to confirm the reliability of the calculated simulation results. Moreover, the article also provides details of flow around submarine like pressure distribution and skin friction on the hull surface of submarine, which serves to many different problems such as in optimizing the hull form of submarine to minimize its resistance. The submarine model employed in this study is the US submarine model DARPA SUBOFF.
