SOLVING INCOMPRESSIBLE THREE-DIMENSIONAL RANS EQUATION BY USING FLUX-DIFFERENCE SPLITTING UPWIND DIFFERENCING SCHEME - A COMPUTATION OF THE FLOW AROUND HSVA TANKER

Under the assumption of double model, after a careful treatment of the grids on the complicated profile of a ship stern, a computation for the flow around the afterbody of an HSVA tanker model and the wake by solving the incompressible RANS equations using the method of artificial-compressibility and flux-difference splitting upwind differencing scheme is presented. The results are compared with experiments, the pressure coefficients Cp from the computation are in good agreement with the test results and the computed flow field qualitatively reflects the actual flow feature. It will provide a useful tool for the further investigation of the interaction between viscosity and free surface, the interaction between hull and appendages, the correlations between full scale ship and models etc. The effects of the different turbulence models, variation in Reynolds number Re and different order of upwind differencing scheme on the computed results are discussed.
