Computations are performed on bare submarine hull DREA and six axisymmetric bodies of revolution with a number of length-diameter (L/D) ratios ranging from 4 to 10. Both structured and unstructured grids are used to discretize the domain around the bodies. Different turbulence models have been tested to simulate turbulent flow. Finally, results computed by 2-D method are compared with published experimental results and found satisfactory.
