摘要：

In the present study, a Rankine panel method (RPM) based on high-order boundary element method is imple-mented in an in-house Fortran code to solve the steady wave problem of high-speed ships. A validation study on both mono-hull and catamaran of Wigley hulls is carried out firstly. The results of resistance and wave profiles show good agreement with experimental data. For a transom-stern hull, two numerical treatments including false body (FB) and three different forms of transom stern conditions (TS) are developed to model the influence of flow separation. RPM incorporated with FB model is applied to evaluate the wave-making resistance of the NPL series hull. Besides, a computational fluid dynamics (CFD) method based on Star-CCM+ is employed to study the flow around NPL 3b and 5365 hull. The computed results of the resistance, wave profile behind the transom stern, and wave pattern around the hull obtained by RPM with TS treatment are validated by comparing them with CFD and EFD results. An NPL 3b catamaran hull is selected to verify the applicability of the present method in the catamaran hull. It's confirmed that the developed Rankine panel method is accurate and robust.
