CFD modelling of liquid–liquid multiphase microstructured reactor: Slug flow generation

One-dimensional CFD model of a multiphase loop polymerization reactor

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, ...

Cfd Modelling of a Negatively Buoyant Purge Flow in the Body of a Reactor Coolant Circulator

The paper describes a finite element flow calculation using a two-equation turbulence model and variable properties, which analyses the effect of injecting a negatively buoyant flow stream into the primary circuit of a gas cooled reactor. This flow is intended to purge moisture laden gas from the compartment housing the electrical motors driving the primary circuit pumps. The study highlights t...

The Indication of Two-Phase Flow Pattern and Slug Characteristics in a Pipeline Using CFD Method

Multiphase flows are commonly encountered in oil and gas industries. The transport of multiphase flow causes the formation of slug, the increase of pressure drop and the possibility of phase changes therefore, a set of simulation runs was performed to predict flow regimes in a horizontal pipeline, and the results were compared with the Baker chart. The effects of small downward inclinations of ...

CFD Analysis of Single and Multiphase Flow Characteristics in Elbow

Computational fluid dynamics (CFD) analysis of singlephase and two-phase flow was performed in a 90 degree horizontal to vertical elbow with 12.7 mm inside diameter. Characteristic flow behavior was investigated at six different upstream and downstream locations of the elbow. To evaluate the effects of different phases, three different air velocities and three different water velocities were us...
