CFD simulations using the Euler–Euler approach are performed to model the gas–liquid bubbly flow in a helical static mixer. The model validation work was based on experiments, which are carried out in a column of diameter 0.08 m packed with helic

Different scales of liquid mixing exist in bubble columns and it is very important to determine the prevailing mixing scale in each flow regime. Two independent parameters were found to exhibit a monotonous decline in the transition flow regime, whic

Capture of carbon dioxide gas from a flue gas mixture (N2:CO2 = 80:20) using amine-impregnated mesoporous sorbent (NETL-32D) was investigated in a small scale batch unit at ambient temperature and pressure. The variation of local bed temperature at d

The identification of the main flow regime boundaries in bubble columns is essential since the degrees of mixing and mass and heat transfer vary with the flow regime. In this work, a new statistical parameter was extracted from the time series of the
