Title : ( The Impact of a Solid Object on to a Liquid Surface )
Authors: Iman Mirzaee Kakhki , Mohammad Passandideh-Fard ,Abstract
In this study, a numerical algorithm is developed for simulating the entry of a solid object into a liquid medium considering the free surface development at the liquid/gas interface. The presented model is that of the fast-fictitious domain method integrated into the volume-of-fluid (VOF) technique used for tracking the free surface motion. The developed model considers the solid objects as fluids with a high viscosity resulting in a rigid motion of the objects. Attributing a high viscosity to solid objects improves the accuracy of the results compared to that of the recent models in the literature without additional computational time and cost. The model is validated by comparison of the simulation results with those of the experiments available in the literature for the free fall of a circular disk and a sphere. For all cases considered, the results were in good agreement with those of the experiments and other numerical studies.
