The present work is about the modeling and the simulation of the interaction of a dense spray of high-velocity liquid particles with liquid surfaces using the FUGU CFD code developed at the MSME laboratory. This study will be conducted using a multi-scale resolution in order to allow the analysis of the mass deposition and the potential secondary ejection (mass and velocity distribution of secondary droplets) after the impact. As a first step, simulations of single impact onto liquid surfaces of different thickness are performed. The main purpose of these simulations is to check that the different mechanisms (crater/crown formation, secondary atomization, bubble entrapment ...) induced by the impingement are well represented. The results are compared to experimental references or other numerical simulations. Then, the same procedure is applied for multi-drop impacts in order to study the behaviour of the above-mentioned mechanisms in the case of the interaction of multiple impacts.
