LARGE SCALE WAVE IMPACTS ON A VERTICAL WALL

This paper treats new large scale measurements of pressure fields on a vertical wall under wave impacts. These measurements were done in collaboration with the Joint Industry Project Sloshel, aimed at sloshing in LNG tanks. Measurements are presented with a relatively high spatial and temporal resolution. The impacts are created by wave focussing at the wall. By changing the focal point with respect to the wall, the impact type was altered. The influence of the impact type on the pressures and forces on the wall at large scale is thus studied.
