Gas-liquid simulation of an airlift bubble column reactor

Airlift bubble column reactors are finding increasing application on industries such as bioprocess industries. The gas-liquid of two-phase fluid flow system has been carried out to investigate the hydrodynamics parameter. An Eulerian-Eulerian approach was used to model air as the dispersed phase wit...
