Resumen
This study proposes a new parameter, the wave front steepness parameter, to better describe the wave slamming coefficient. Four cases of wave breaking were employed to study the relationship between wave front steepness and wave slamming coefficients. Based on model results with OpenFOAM, an empirical formula was derived to relate the slamming coefficient to the wave front steepness.Referencias
