Volume of Fluid Method (VOF) is a good alternative to Finite Element Method for complex simulations1 which involves fluid flow because it offers a good solution for very cell of the domain. Air lift pump system uses the principle of two communicating vessels that are filled with two or more fluids. The fluids can be partially or totally immiscible one with another. The VOF method together with Multiphase (Eulerian) model provides a very good approach for determining the qualitative interaction of the two fluids. In our study we simulated how compressed air flows into a pipe that is submerged into water and due to diffusion they create a new fluid that is less dense than water, but heavier than air. The new fluid will rise higher against the water level, which creates an absorption. For industrial applications we can name ecological fishing, cleaning underwater relics etc.
