چکیده
|
This paper presents 2-d finite volume method for computation of viscous drag based on reynolds-averaged navier-stokes (rans) equations. 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.
