Computational investigations and grid refinement study of 3D transient flow in a cylindrical tank using OpenFOAM

The study of physic fluid for a liquid draining inside a tank is easily accessible using numerical simulation. However, numerical simulation is expensive when the liquid draining involves the multi-phase problem. Since an accurate numerical simulation can be obtained if a proper method for error est...
