Grid Generation and Airwake Simulation on Ship

Abstract:

Dynamic characteristics of flow field on the ship deck are complex. CFD(Computational Fluid Dynamics) results of LHA ship were verified the accuracy of numerical simulation through compared with the experimental data. Three different grids were generated to discuss and analyze the influence of the prismatic layer grid. The results show that, the presence of prismatic layer grid does not affect the results. With calculating the full-size aircraft carrier ship, the mechanical evolution of vortices in the ship deck airwake field was found. The results can provide an important reference for engineering calculation of the fluid dynamics and establish best design method early in a ship's planning stage.
