Abstract
Results are reported of concurrent and complementary experimental and computational investigations on surface ship hydrodynamics at Ship Research Institute of Japan. The main goal of the investigations is to conceive an integrated hydrodynamic design system that can be utilized in shipbuilding industry. Model scale experimental data, which include global force and local flow measurements, are obtained by towing tank experiments. The experimental data provide validation benchmark for computational fluid dynamics simulations and are complemented by the results of computational investigations in terms of high-resolution data and turbulence quantities. The computational results also provide the global force and local flow data and are complemented by experimental data in various aspects such as breaking waves and sinkage and trim of the hull. The uncertainty assessment for experiments and the verification and validation for computational results provide the level of uncertainties and errors. Through the overall procedure that includes experimental and computational investigations with careful uncertainty analysis, an extensive set of information that can be provided to aid field designers is obtained. The future work includes further application to wave breaking and maneuvering ships in ambient waves using an unstructured grid method computer code and building a simulation-based-design system that comprises the information obtained throughout these investigations.
