Résumé

Estimating the oil-water temperatures in flowlines is challenging especially in deep or ultra-deepwater offshore applications where issues of flow assurance and dramatic heat transfer are likely to occur due to the temperature difference between the fluids and the surroundings. Heat transfer analysis is very important for the prediction and prevention of deposits in oil and water flowlines, which could impede the flow and give rise to huge financial losses. Therefore, the development of a 3D Computational Fluid Dynamics predictive tool for heat transfer analysis is significant to serve the need in exploring the technologically demanding and hostile subsea deepwater fields. In this work, a non-isothermal two-phase flow model is first developed and then implemented in the InterFoam solver by introducing the energy equation using OpenFOAM ® code. The Low Reynolds Number (LRN) k-ε turbulence model is utilized to resolve the turbulence phenomena within the oil and water mixtures. The flow patterns and the local heat transfer coefficients (HTC) for two-phase oil-water flow at different flowlines inclinations are validated by the experimental literature results and the relative errors are also compared. Thereafter, HTC and flow patterns for oil-water flows at downward inclinations angles can be predicted by the models. The velocity distribution and temperature variation at the flowline cross-sections are simulated and analyzed in detail. Consequently, the numerical model can be generally applied to compute the global properties of the fluid and other operating parameters that are beneficial in the management of twophase oil-water transportation.
