Abstract
The objective of this work was to develop a model to calculate the slip velocity between the phases in an isothermal flow in horizontal pipes in the water-in-oil dispersion pattern. The model was formulated from the linear momentum conservation equations of the liquid mixture and the dispersed phase (water) and an algebraic slip relation was derived. A swarm function taking into account the concentration of dispersed phase was incorporated and fitted for the conditions of interest. The results obtained for the phase velocities were compared with experimental data with satisfactory agreement.
