A Model for Temperature Prediction for Two Phase Oil/Water Stratified Flow

Abstract

In this paper a mathematical model was developed to predict temperature profiles for twophase oilwater stratified flows. Based on the energy balance of a control volume, analytical solutions were derived for the prediction of temperature profiles for twophase oil/water stratified flow pattern in pipe flows. The model has been verified with a singlephase heat transfer model, which is available in most heat transfer textbooks. Two typical cases were simulated for extreme operating conditions with water cuts of 0% and 100%, respectively. This analytical model was also validated against experimental data. The test was conducted on a multiphase facility with accurate flow control devices and effective thermal treating units. The water cut was set at 50% for this test. The simulation results and experimental data agree within the experimental uncertainty. The closure relationships can be conveniently applied to a twophase oil/water paraffin deposition model, which is dependent on the heat transfer process. The model was also used to predict the temperature profiles for twophase oil and water flows with different water cuts.
