In the present work different numerical methods, namely a free surface RANSE solver and Smoothed Particles Hydrodynamics (SPH) method, this last currently under development at DINAV, have been applied to the evaluation of slamming loads (global forces and local pressures) on a typical wedge shaped section with 30° deadrise, for which experimental data (drop tests with a free falling rig) at different heel angles (ranging from 0° to about 30°) were available. Results from both methods are presented and compared with available experiments, allowing to make an assessment of these different techniques and to stress their relative merits and shortcomings.

Abstract
In the present work different numerical methods, namely a free surface RANSE solver and Smoothed Particles Hydrodynamics (SPH) method, this last currently under development at DINAV, have been applied to the evaluation of slamming loads (global forces and local pressures) on a typical wedge shaped section with 30° deadrise, for which experimental data (drop tests with a free falling rig) at different heel angles (ranging from 0° to about 30°) were available. Results from both methods are presented and compared with available experiments, allowing to make an assessment of these different techniques and to stress their relative merits and shortcomings.
