| Abstract: | In this paper, the finite volume method (FVM ) for solving the Reynolds-averaged Navier-Stokes equations of three-dimensional viscous flow around ship stern in non-orthogonal body-fitted coordinates (BFC) has been introduced. The Navier-Stokes equations and the continuity equations in Cartesian coordinates are transformed into a generalized curvilinear coordinates by using finite difference approximations in the trans-formed domain. The solutions of the finite difference equations are obtained iteratively by using a pressure-veloc-ity correction algorithm (SIMPLE-C). Finally, calculating example of SSPA-720 are given. |
