A relation which defines the drag of spherical particles in more or less concentrated suspensions was employed to describe bubble column behaviour in the uniform bubbling regime. General validity of the relation under low density ratios of dispersed to continuous phase was shown by evaluation of flu
## Abstract The hydrodynamic behavior of a singleβstage tapered bubble column using an airβwater twoβphase system has been studied. The experimental results indicate that the holdup increases with increasing superficial gas velocity and bubble slip velocity, while it remains constant with increasin
Gas holdup data in multistage bubble column is analyzed through slip velocity incorporating pseudo hydrostatic effect, momentum transfer effect, particle-to-particle and particle-to-wall effects and coalescence effects. The bubble size, required for the estimation of single bubble rise velocity, is
