摘要：

The water-modelling of the ejection rate of overflow generated by air-lift pump has been studied under various operating conditions, namely, top pressure, gas flow rate, nozzle submergence, riser diameter and lift ratio, The churn-turbulent flow, consisting of distorted bullet-shaped bubbles, was predominant in the flow regime, The decrease of top pressure and the increase of nozzle submergence have the same effect as the increase of gas flow rate on the ejection rate of overflow. The ejection rate of overflow increased as top pressure decreased, nozzle submergence increased, gas flow rate increased, lift ratio decreased and/or riser diameter decreased.
