Linear and nonlinear analyses of the porpoising dynamics of high-speed planing craft using full-scale trial data

Investigation of the optimum longitudinal single transverse step location for a high-speed craft

“…It was noted that mesh advancements do not alleviate this problem. In most cases, this issue might result in an unintended drag decrease of up to 30% [25]. In the current study, the phase replacement technique was used to address this problem, as reported by [25].…”

“…In most cases, this issue might result in an unintended drag decrease of up to 30% [25]. In the current study, the phase replacement technique was used to address this problem, as reported by [25]. This approach replaces the water phase with the unwanted air phase in the specified locations.…”

“…4. Table 2 The model's and the boat's geometric and hydrostatic specifications (the hull with no-step) [25].…”

“…As shown in Fig. 2, the finite volume mesh was constructed utterly in [25] comprising structured hexahedral grids, and the mesh assessment is given in Table 1. Walls with slip boundary conditions were employed in the far field.…”

“…As also mentioned in [30], several experimental methods are available for evaluating the trim and sinkage attitudes of models in the basins. During the model testing, the fore-and-aft point running sinkage measurements, which are collected by laser distance meters, were used to derive the trim angle values [25].…”
