This paper investigated the problem of overall gas holdup and the oxygen mass transfer in the internal loop airlift reactor by numerical modeling and experimental validation. The population balance model (PBM) was introduced as the general model to characterize the bubble behaviors, i.e., bubble breakage and coalescence. Bubble coalescence, as a result of fluid turbulent eddy, bubble rise difference,...
Gas-liquid systems form a key component of many chemical industry processes. In such systems, the knowledge of the gas volume fraction, its distribution and its eventual effect on mass transfer and reactions is absolutely essential. Experimental measurements have allowed to look into such systems to a good level of details, resulting in numerous correlations, which are commonly used in the design...
