✦ Synopsis

A new type of bioreactor, in which two liquid phases are used, is introduced and a model description of its hydrodynamic behavior is given. The model is based on the two-phase drift-flux model of Zuber and Findlay and on a friction coefficient derived from one-phase flow theory. Drop sizes, necessary for model calculations, were estimated from literature correlations and photographically verified. The model predicts the continuous-phase circulation velocity and dispersed-phase hold-up within an accuracy of 5% for a pilot-plant reactor, and within 10% for a lab-scale reactor. Only at very low ranges, especially on lab scale, is this accuracy not attained.

## Abstract Oxygen transfer in the liquid‐impelled loop reactor is described for a setup in which the perfluorochemical FC40 is aerated externally. Two sizes of reactors are investigated. The mass‐transfer coefficient __k__ appears to be lower with a factor of about 0.6 compared to gas liquid syste

The hydrodynamic model of Young et al. (1 991) for external-loop gas-lift reactors was modified to account for buoyancy forces in the gas phase. The revised model is based on macroscopic balances for the gas-liquid separator and external downcomer and spatially-averaged, 1-D mass and momentum balanc

The hydrodynamics of high liquid holdup airlift reactors have not been widely studied. In this work we study the riser of a reactor of this type, focussing on the in¯uence of the gas ¯ow rate and the submergence ratio on various hydrodynamic parameters: liquid circulation velocity, gas holdup, and g
