The transient flow of immiscible liquids by using rotational motion is investigated. The solution was calculated by solving the transient 2-D momentum, continuity, turbulence equations by using Volume of Fluid method. The dynamics of entrained fluid which is penetrated in to other has been studied. To analyse it we used one rotor and two rotor system inside two different size of conduit. Two phase i.e. water-kerosene and three phase i.e. water-kerosene-diesel flow has been used to carry out the simulation. All the results obtained through the numerical simulations are used to make the effective analysis of entrainment phenomenon of the multiphase flow and also helpful to make comparative study on volume fraction. The presence of complex fluid topologies and multiple fluid flow over a cylinder is a challenging computational problem. The present paper establishes the study of entrainment phenomenon between two and three fluid pair (i.e. water-kerosene, water-kerosene-diesel, water-petrol) using rotational motion.
