Recent progress in CFD modelling of multiphase flow in horizontal and near-horizontal pipes
Computer simulations of two-phase gas-liquid pipe flow cases have been performed with the commercial code STAR-CD using the VOF method and the results are illustrated in this paper. Computed pressure losses for stratified flow and stratified-wavy flow and time-averaged liquid levels are compared against measured data, showing good agreement with the experimental data. To achieve these results, ...
متن کاملUpscaled Modeling in Multiphase Flow Applications
In the paper we consider upscaling of multiphase flow in porous media. We propose numerical techniques for upscaling of pressure and saturation equations. Extensions and applications of these approaches are considered in the paper. Numerical examples are presented.
متن کاملA Dynamic Simulation of Annular Multiphase Flow during Deep-water Horizontal Well Drilling and the Analysis of Influential Factors
A gas kick simulation model for deep-water horizontal well with diesel-based drilling fluid is presented in this paper. This model is mainly based on the mass, momentum, and energy conservation equations. The unique aspect of this model is the fluid-gas coupling and the change of mud properties after the gas influx from the formation. The simulation results show that the gas in an annulus disso...

متن کاملModeling multiphase flow using fluctuating hydrodynamics.
Fluctuating hydrodynamics provides a model for fluids at mesoscopic scales where thermal fluctuations can have a significant impact on the behavior of the system. Here we investigate a model for fluctuating hydrodynamics of a single-component, multiphase flow in the neighborhood of the critical point. The system is modeled using a compressible flow formulation with a van der Waals equation of s...
