N2 - The hydrodynamic performance of high-speed planing hulls has gained considerable interest, with recent advancements in computational fluid dynamics and hull design techniques enhancing the understanding of planing hull hydrodynamics. In this study, we conducted a numerical investigation using the Reynolds-averaged Navier-Stokes approach with overset grids to capture large motions at high speeds. This study aims to improve the hydrodynamic performances of planing hulls, specifically focusing on total resistance, trim, and sinkage. The initial Fridsma hull with a deadrise angle of 20° has been used for validation, demonstrating good agreement with measurements at different Froude numbers. Subsequently, new configurations based on the Fridsma hull have been designed by varying the deadrise angle, number of chines, and transverse steps. Our findings reveal a correlation between the deadrise angle, the number of chines, and the Froude number. As the deadrise angle increases, total resistance also increases. Additionally, a single chine yields superior results at higher Froude numbers, while multiple chines offer advantages at lower values. The introduction of transverse steps consistently increases total resistance, highlighting their role in improving planing hull performance. This research not only offers valuable insights into planing hull design but also leverages state-of-the-art numerical methods to advance the understanding of hydrodynamic behaviors at high ship speeds.
