3-DIMENSIONAL FLOW SIMULATION ON HIGH-PERFORMANCE COMPUTERS

A numerical method for calculating three-dimensional, steady, incompre ssible, viscous flows is described. The conservation equations for mas s and momentum and the equations of the k, epsilon-turbulence model al e solved with a finite volume method or? nonorthogonal boundary-fitted grids. The method employs cell-centered variable arrangement and Cart esian velocity components. The SIMPLE-algorithm is used to calculate t he pressure and to enforce mass conservation. The computer code is vec torizable as far as possible to achieve an optimal performance on mode rn vector computers. Results of laminar and turbulent flow calculation s in 90 degrees bends with circular and square cross section and in th e stator of a hydrodynamic torque converter are presented.
