CFD Study of Gas-liquid Hydrodynamics in a Bubble Column

This paper presents a computational fluid dynamics (CFD) of the gas-liquid flow in a bubble column. Multiphase simulations were performed using an Eulerian-Eulerian two-fluid model besides considering the drag coefficient model suitable for spherical and distorted bubbles. The interfacial force mode...
