The eccentric annular flow is a flow with special considerations; it forms a vital part of practical industrial flow analysis. In this work eccentric, dual phase flow through horizontal wells are simulated with the help of CFD. In horizontal annuli, flow occurs in an adverse pressure gradient condition, that makes the particle inside it susceptible to reversed flow. Thus the flow has to be analyzed in a three dimensional manner. Moreover, the non-Newtonian behavior of the fluid makes the problem really challenging in numerical and physical aspects. The results of this work clarify the relationship between different flow characteristics with the speed of inner wall rotation. The flow characteristics include swirl of flow, wall shear stress, and axial velocity.
