In this research a 5mm 3D microchannel was simulated using CFD solver, where the multi-phase model with constant wall tension (0.005N/m) was implemented using two fluids water/ oil15W-40, the results presented the effect of inlet velocity on the flow performance, where the model was assumed as laminar flow model. Additionally, the shear stress at walls were calculated due to velocity gradient change . Generally, two-phase dispersion of oil-water in the flow, like that of petroleum droplets, is commonly used  in the  oil  industry.  Dispersion are  often  considered  unfavorable  during oil  production because they increase the effectiveness of the system's fluid viscosity, resulting in increased pressure decreases. However, emulsions contribute to problems in oil-water separation.
