Numerical Study on Propulsion and Seakeeping Performance of a Ship Using Eulerian Scheme with Lagrangian Particles

The power required must be determined appropriately to tow a ship, and ship performance must be predicted realistically with respect to a ship safety in the sea. Consequently, developed CFD design tools and techniques for predicting a performance are necessary in ship design stage. In our previous researches, we have developed a numerical method, i.e. Eulerian scheme with Lagrangian particles, for computing a strongly nonlinear interaction between ship and wave with breaking. Firstly, in this study, the developed model is applied to evaluate propulsion performance of a fishing boat. We also applied the model to investigate seakeeping performance of a high-speed ferry. The resistance and motions, e.g. heave and pitch, were in good agreement with experimental results and the strip theory, In addition, we also discussed pressure distribution, velocity field and free surface motions around the fishing boat and high-speed ferry in waves with breaking. We showed that the Eulerian scheme with Lagrangian particles would provide a highly accurate solution and also would be usefulness and effectiveness as a ship design tool.
