Numerical study of the wave impacts generated in a wet dam break

This paper focuses on the numerical analysis of different wave impacts generated in a wet dam break by varying downstream depth and position obstacle. With this relatively simple set-up, five hundred were simulated, providing comprehensive dataset covering four classical impact types : sloshing, flip-through, aerated broken impacts. We determined parameters for which flip-trough occur showed that among all flip-through impacts, there is one optimum generating pressure peak larger others. Compared to pressures recorded or simulated with flow most previous studies, present work reached values order magnitude larger. Therefore bottom, it seems possible generate strong short duration. has be verified experimentally specifically focusing measurements repeatability due obvious effect gate dynamics subsequent flow. When if confirmed, set-up could used validate models without need long propagation stage before impact. • Numerical study obstacle position. All obtained through adjusting parameters.
