In this paper, the flow of liquid-liquid two-phase flow in vertical and inclined pipes has been investigated numerically. The simulations of kerosene-water flow in a pipe of 77.8 mm inner diameter and 4500 mm length have been carried out using two-fluid model. The ANSYS Fluent 14.0 was used to solve the mass and momentum equations incorporating the interface forces and the standard k-ε model with the standard wall function to describe the turbulence in the flow. The simulation was carried out for superficial water velocities of 0.29, 0.6, 0.9 and 1.2 m/s and three volumetric qualities of 9.2%, 18.6% and 40% at three different inclination angles of 0°, 5° and 30°. The predictions included volume fraction, water velocity and drops velocity. The results from Fluent for vertical pipe were compared with the experimental data from literature to check the accuracy of meshing, physical model and boundary conditions used in predictions. The model predictions showed a good agreement with experimental data obtained for the vertical pipe. Accordingly, the same geometry, meshing, physical model and boundary conditions were used for inclined pipes. Keywords: kerosene-water flow, vertical and inclined pipe, CFD simulation.
