EXPERIMENTAL STUDY ON THE GAS-LIQUID FLOW IN THE MEMBRANE MICROPORE AERATION BIOREACTOR

Particle image velocimetry (piv) has been developed to measure the typicaltwo-phase flow of various work conditions in membrane micropore aerationbioreactor (mmab). the fluid phase is separated out using image processingtechniques, which provides accurate measurements for the bioreactor’s flowfield, and makes it possible for quantitative analysis of the momentumexchange, heat exchange and the process of micro-admixture. the experimentalmethod piv used in this paper can preferably measure the complex flow in thereactor and initiates a new approach for the bioreactor design which mainlydepends on experience at present.
