The present paper presents a numerical simulation of a water droplet falling under a constant velocity onto a liquid pool. The governing equations are solved using the control volume approach on a non-staggered grid system. The topological changes of the liquid droplet and the liquid surface are predicted by means of the level set method. The obtained results showed that the numerical method developed is capable to predict the resulting dynamics of such complex phenomenon in a simplified and accurate way. The remarkable capability of the developed numerical method in predicting two-phase flow dynamics enables us to predict further a wide range of two-phase flow industrial and engineering applications.
