Summary: | Airlift Pump technology is briefly summarized and the potential application of airlift
technology to low-lift, low-submergence, high-flow applications such as open channel
flow in urban storm drainage, is explored. Four experimental setups are described,
including one prototype urban storm drainage installation. Three descriptive models for
airlift pump operation are developed and one adopted for application in low-lift, low-submergence,
high-flow applications. The model allows a simple design procedure for
airlift pumps in this regime. A simple design hand-calculations procedure is developed,
and two personal computer-based implementations are described. A simple design
example is presented and recommendations for further research and development
directions are made. === Applied Science, Faculty of === Civil Engineering, Department of === Graduate
