要約

The heat transfer characteristics of fully developed stratified wavy oil-water no-Newtonian two phase flow in the long-distance pipeline are studied numerically in this paper. A coupled mathematical model of non-Newtonian stratified flow under non-isothermal condition is proposed and solved in bipolar coordinate system. LES model is utilized to simulate the turbulence flow and the wall attenuation function is used to describe the inadequacy performance of wavy oil-water interface. Temperature and Pressure drop along the pipeline are predicted successfully. The heat transfer characteristics of oil-water two-phase flow are studied in detail by analyzing the temperature distribution at pipe cross section. Furthermore, velocity distribution and temperature value at pipe wall and oil-water interface can be obtained. The effects of operating parameters on the temperature drop process along the pipeline are also studied. Thus, the results show the ability of the numerical model to investigate heat transfer in oil-water two-phase flow in pipeline.
