ABSTRACT: Over the past two decades high-speed vessels have extended their
service areas from protected waters to the open ocean where frequent and large
water impacts can result in structural damage. The accurate prediction of
slamming loads, and their consequences on light-weight high-speed vessels, is
an essential element of efficient structural design. The aim of this work is to
understand and accurately predict the behavior and local slam loads of quasi-2D
wedge shaped hull forms impacting water. The computed results, using
finite-volume Computational Fluid Dynamics (CFD), are validated against drop
test experimental data and compared to a previously published numerical simulation
using Smoothed Particle Hydrodynamics (SPH). The CFD results show good
agreement with the experimental measurements.
