CFD Modeling in Multiphase Flow Transport/Separation Equipment

Dear Colleagues,

Multiphase flow transport/separation equipment are devices employed for transporting multiphase mixtures or separating one phase from another. They are widely applied in air pollution prevention, petroleum, the chemical industry, natural gas, nuclear power, shipbuilding, seawater desalination, and other industries. Based on the various mechanisms and application fields of multiphase flow transport/separation, gas–liquid separators, cyclone separators, vane separators, demisters, gas/liquid cylindrical cyclones (GLCCs), liquid–gas jet pumps, gas–liquid pumps, gas–liquid vortex pumps, liquid–solid jet pumps, air lift pumps, gas–solid ejectors, and other technologies have been formed with various structures.

In the actual operation of multiphase flow transport/separation equipment in various industries, due to the complex interaction between gas, liquid, bubbles, droplets, particles,  and liquid film, the internal flow and separation processes are extremely complex. Limited by experimental technology, cost, and other factors, these complex phenomena are difficult to observe and test, while CFD technology can make up for this deficiency. Therefore, scholars are increasingly employing CFD technology in order to carry out performance prediction, structure optimization, and flow and separation mechanism research. Due to the complexity of multiphase flow, CFD calculation still presents many challenges in the modeling, simulation, and analysis of these equipment.

The purpose of this Special Issue is to gather new research contributions on CFD calculation and the analysis of multiphase flow transport/separation equipment (in the form of research articles, review articles, and brief communications). We welcome submissions from various research fields, from science to engineering, addressing theory, simulation, and application. The topics of this Special Issue include, but are not limited to, the mechanism and process of oil–gas transport/separation, steam (air)–water transport/separation, liquid/gas–solid transport/separation, equipment design and optimization, and application expansion.
