Use of Commercial CFD Codes to Enhance Performance Prediction Capabilities for Planing Boats

摘要

Commercial CFD codes have become common tools for evaluating hydrodynamic performance of marine components such as propellers and appendages. The codes have traditionally been limited to submerged, single-phase flow and displacement vessels. New modeling capabilities within these codes have extended their potential application to free surface problems and cavitating or ventilated flows. Mercury Marine has been evaluating the use of these codes for analyzing planing boat performance with the inclusion of appendages, propellers, tabs/interceptors, and their interactions. Validation cases and results of this investigation will be presented with recommendations for the application of these codes.
