Gas holdup and longitudinal dispersion in different types of multiphase reactors and their possible application for microbial processes
Gas holdup and liq. phase longitudinal dispersion were detd. in concurrent 1- and 6-stage, 2-phase bubble columns, and in countercurrent 1-stage, 2- and 3-phase bubble columns, using the longitudinal dispersion and backflow cell models to describe the intensity of longitudinal mixing. The axial dispersion model in conjuction with Monod growth kinetics were used to examine the influence of fluid mixing on the performance of a microbial process. [on SciFinder (R)]
