Deep seawater commands much attention recently because of its low temperature, rich nutrition.and cleanliness. For the purpose of drawing up deep-sea water constantly and inexpensively, the authors are considering to use air-lift pump. This report describes both the.experimental and analytical investigation for air-lift pump performance in case of being used for drawing up deep-sea water. The numerical simulation code based on two-fluid (gasliquid) model was developed, and the results were compared with that of experiments. Consequently, the analytical volume flow rate of lifted water was proved to have a tendency to be larger than that of experimental one in cases the length of suction pipe was quite long, or void rate was very small.
