It is well known that slamming and whipping can significantly contribute to a ship’s structural loading which can severely impact a ship’s operational safety. Therefore, a method of predicting severe transient structural loads is needed, especially for the design of future high-speed patrol boats and high-speed ferries. A number of computational fluid dynamics (CFD) codes have demonstrated the ability to cope with complex body shapes and to numerically capture the nonlinear effect of hydro-elasticity. However, validation is scarce both due to a lack of experimental data and the computational intensity of the problem.
This paper describes a validation study of a Reynolds averaged Navier-Stokes (RANS) code (STAR-CCM+) and a Lagrangian-Eulerian fluid structure interaction (FSI) code (DYSMAS) using 10 degree wedge drop test experimental data obtained at the Naval Warfare Center, Carderock Division, December 2010.
