Good knowledge of the extent of gas dispersion in the liquid phase, mass transfer parameters (interfacial area and mass transfer coefficients), pressure drop characteristic and energy dissipation is essential for the modeling, design and optimization of bubble column.
The present work consists of a systematic study on gas entrainment and ejector performance, gas dispersion (gas holdup), bubble size distribution, pressure drop analysis, mass transfer characteristics and energy analysis for cocurrent gas-liquid two-phase downflow system. The variations of different parameters with different operating and geometric variables were investigated meticulously. The experimental results have been analyzed by established models. Some correlations were also developed to analyze the data in terms of physical, operating and geometric variables.
