摘要：An unstructured mesh method is expected to be an efficient tool for CFD analysis around complex flows, in contrast to structured mesh method. However, mesh generation around a complex geometry is still time-consuming and high-quality unstructured mesh for viscous flows is difficult to generate. A hexahedral unstructured mesh system with local refinement has merits of both structured and unstructured mesh system, and in addition, it offers an automated and robust mesh generation procedure.In this study, a hexahedral unstructured mesh was adopted for analysis of flows around twin-skeg ships. First of all, the accuracy of the computed results including grid dependence was investigated by comparing with experimental data and computed results on structured mesh. Secondly, the flows with different tunnel slope angles and horizontal skeg distances were computed and the ship resistance and propulsion performance of the twin-skeg ships were discussed.
