Numerical simulation of oil-water non-Newtonian two-phase stratified wavy pipe flow coupled with heat transfer

Research on water content measurement method based on heat transfer method

“…When measuring physical parameters by heat tracing technique using heat transfer method, high power heater is required for better results, in this paper, in order to overcome the high power heater, a variable power circuit will be used to heat the sensor and detect the temperature of the heated sensor to calculate the water content. Li, Y et al [ 11 ] established a coupled mathematical model for oil water non Newtonian stratified bellows flow under non isothermal conditions. Then, the oil water non Newtonian two-phase stratified corrugated pipe flow process was simulated.…”

“…A clear understanding of the heat transfer mechanism is helpful to the accurate calculation of water content. In this paper, based on reference [ 11 ], the measurement mechanism model of this paper was deduced, while the correctness of the model was verified using computer simulation software. Finally, the functional relationship between water content and heat transfer coefficient was calculated and the value of water content was determined.…”

Numerical study and sensitivity analysis of two-phase oil-water flow and heat transfer in different flowline orientations using OpenFOAM

“…The authors reported that the simulated result from the analytical model was only validated for the water cut of 50% and verified for the water cuts of 0 and 100%. Generally, all authors deduced the complication in predicting the heat transfer rate on the complexity of two-phase oil-water flow [41,42].…”

Hydrodynamic Modeling of Oil–Water Stratified Smooth Two-Phase Turbulent Flow in Horizontal Circular Pipes

“…However, this model is only suitable for oil-water laminar flow conditions. Later, Li [32] firstly applied the two-dimensional flow model of gas-liquid to oil-water liquid-liquid flow to research the non-Newtonian characteristics of oil-water stratified flow on horizontal pipes. However, compared with the gas-liquid two-phase flow, the oil-water two-phase flow has significant differences, mainly due to the small oil-water density difference, the small viscosity difference, and the small velocity difference between the two phases.…”
