説明
An unstructured grid method for simulating three-dimensional incompressible viscous flows is presented. The governing equations to be solved numerically are the Navier-Stokes equations with artificial compressibility. The spatial discretization is based on a finite volume method for unstructured grid system. Second order accuracy in space is achieved using a flux-difference-splitting scheme with MUSCL approach for inviscid terms and a central difference scheme for viscous terms. Time integration is carried out by the backward Euler method. The linear system derived from the linearization in time is solved by the Gauss-Seidel iteration. For the analysis of high Reynolds number flows, the one equation turbulence model proposed by Spalart and Allmaras is used. The turbulence equation is solved in a similar way as the Navier-Stokes equations. Brief description of the numerical method is given together with some computational results for flows around a 2 D wing section and a ship form.
