... to be met. In this paper, the numerical simulation with three different turbulent models, Reynolds averaged Navier Stokes(RANS) Realizable k- model, RANS SST(Menter's Shear Stress Transport) k- model and the large eddy simulation (LES) are used to simulate the self-propulsion of DARPA SUBOFF submarine...

... of flow past a stationary circular section. A dynamic Large Eddy Simulation (LES) turbulence formulation is used to ensure important features of the drag crisis are captured. Further simulations are presented where the cylinder is free to oscillate in two directions, parallel and normal to the direction...

... structures partly submerged in water. A three dimensional unsteady flow around a rectangular cylinder is studied for four different submergence ratios by using computational fluid dynamics (CFD) tools with LES turbulence model. Simulation results are compared to particle image velocimetry (PIV) measurements...
