NUMERICAL STUDY ON AIRLIFT PUMP PERFORMANCE FOR DRAWING UP THE DEEP SEA WATER

摘要

For the purpose of predicting performance of airlift pumps in deep seawater, a one-dimensional numerical simulation code based on the two-fluid model has been developed. In order to verify the numerical simulation code, an in-situ experiment on lifting up seawater from 30m depth was carried out at sea and the results were compared with predicted performance. Furthermore the performance of airlift pump at the larger water depth (up to 1500m depth) was discussed with the developed numerical simulation code.
