Abstract
The paper presents free-surface RANSE computation of a planing craft taking into account dynamic sinkage and trim. The method has been validated with towing tank experiments. The response of the boat to incident waves, vertical acceleration and hydrodynamic impact loads acting on it is also presented. Rigid body motion of the boat and wave dynamics has been implemented in the RANSE solver through user codes. Reynolds Stress model has been used to model the turbulence. Apart from the hull motion and load computation, the paper also provides the validation results for the RANSE computation of water entry problem of a typical wedge section. © 2008: The Royal Institution of Naval Architects.
