In this paper the models of a theoretical tank and a real size draining vessel are described and numerically simulated. The main idea is to demonstrate the Toricelli’s law theorem for fluid dynamics for ideal liquid both for a theoretical vertical cylindrical tank and for a different geometry horizontal vessel of the same volume as the tank and compare the total time of liquid leaving the space of both of the reservoirs. The simulation is a multiphase problem containing two phases, which are water and air, is based on the VOF (volume of fluid) method discrete elements method (DEM) for simulating the sand bed formation for outlet nozzle capacity evaluation. As a result there are two-phase (gas-liquid) models of an “ideal” tank and an industrial vessel numerically calculated for determining and comparing the total time of water draining, and an extra model showing the dependence of sediment layer thickness on the outlet nozzle capacity.
