WebTow tank testing of high speed planing craft differs from traditional displacement hull testing in several aspects, even when the objectives are similar. While the sinkage and trim of a displacement ship does change with speed, the changes are relatively small and do not result in large changes to their waterline length and wetted surface area. Planing craft, … WebJan 18, 2024 · For computation with this configuration and using a medium grid (approx. 5.9 M cells), predicted sinkage and trim, dynamic overset, propeller effect and nonzero drift angle, it takes approximately 96 h to obtain a statistically converged solution, e.g., the fluctuation amplitudes in the time histories of forces, moment, sinkage and trim are ...
