Ship hull automatic optimization techniques research based on CFD

The article briefly elaborated the ship hull optimization research development of domestic and foreign based on CFD, proposed that realizing the key of ship hull optimization based on CFD is the hull form parametrization geometry modeling technology. On the foundation of the domestic and foreign hull form parametrization, we proposed the ship blending method, and clarified the principle, had developed the hull form parametrization blending module. Finally, we realized the integration of hull form parametrization blending module and CFD using the integrated optimization frame, has realized hull form automatic optimization design based on CFD, build the foundation for the research of ship multi-disciplinary optimization.
