Numerical Study on the Effect of Turbulence Models on RANSE Computation of Flow Around Submarine

In numerical simulation, choosing an appropriate turbulence model plays an important role in prediction resistance of the ship in general and of submarine in particular. This paper investigates the effect of turbulence model on flow around the submarine in submerged condition using RANSE method. The numerical obtained results indicate differences of flow around submarine in terms of resistance, shear stress and pressure distributions on submarine surface. It is recommended that the SST $\mathbf{K}-(\omega)$ turbulence model should be used with respect to level of accuracy. The submarine model used in this study is the US submarine model DARPA SUBOFF.
