摘要：

The objective of the current work is to study numerically the influence of large variations of Weber (We) and Reynolds (Re) numbers on the global wave shape just before impact of a Single Impact Wave (SIW) - a wave generated from initial condition at rest and leading to an impact on a wall. The reference SIW is generated in 2D with water and air in a wave canal. The water is initially at rest with a free surface presenting a large bump close to one of the vertical walls. A bathymetry is located in front of the other vertical wall. This wave leads to a large, entrapped gas pocket after impact. Different calculation cases are chosen to analyze the influence of the We and Re number variations when studying the reference SIW at small scale, keeping the same fluids. Simulations are performed using a two-phase flow with surface tension high-fidelity front-tracking software developed at Polytechnique Montreal. The global wave shapes and variations of the total energy composition in the system are compared for the different cases.
