MODELLING WAVE-STRUCTURE INTERACTION WITH A NEW COMPRESSIBLE TWO-PHASE FLOW SOLVER

This contribution presents and investigates the effects of air entrainment compressibility on shape magnitude wave impacts occurring at crown walls top sea defenses. To this purpose, a new solver, developed in OpenFoam environment to represent interactions with impermeable porous coastal structures, accounting for fluid compressibility, is checked against recent laboratory tests overtopping impacts. By comparing first results code ones obtained native solver dealing incompressible fluids exclusively, significant advances representation pressure signals peaks seem be achieved.
