The present work is an investigation of fluid-fluid two-phase flow past a cylinder. Ansys Fluent 13.0 software has been used to know the flow patterns. Volume of Fluid (VOF) technique is used to track the liquid-liquid interface. Volume of fluid multiphase flow approach is capable of predicting the overall performance of liquid-liquid two- phase flow. In the present work two immiscible liquids of different viscosities are flowing side by side in different phases. The flow patterns are related with the capillary and Reynolds numbers. The capillary and Reynolds numbers are quite small and therefore, flow is laminar and the shape of the interface between the immiscible liquids is controlled by the viscous forces and the interfacial tension. Therefore, viscous forces and surface tension forces are the main dominant forces in the present model. Therefore, the gravity force can be neglected because it has very less effect as compared to viscous and surface tension forces. So the gravity force has been neglected in the present work whereas the viscous force plays a dominant role.
