Ahslract~as hold-up and hqmd phase longrtudmal dlsperslon have been measured m concurrent one-and SIX-stage two-phase bubble columns as well as m counter-current one-stage two-and three-phase bubble columns To descnbe the mtenslty of the lon@udmal nuxmg the log~tudmal dlsperslon and the backflow cell models were apphed The possible mfluence of fled nuxmg on nucrobml processes was mvest@ed INTRODUCITON Bubble columns gam mcreasmg unportance as gas-hqud reactors for contmuous fermentation processes The behavlour of contmuous reactor systems has often been represented by the plug flow modei, the completely rmxed model and the dlsperslon model These three dlflrerent models depend on the degree of longitudmal dlsperslon of me&a Fermentations are mostly carried out m the conventional stied-tank type vessel The flow behavlour of many contmuous systems bees between the two ideal cases Examples for such models are the axml drsperslon model or the N-tanks-m-serves model These modeIs contam parameters which descnbe the degree of lonBtudmal dlsperslon For autocatalmc reactions such as those associated with many blochermcal processes Blschoff [I] showed
