Abstract

The flow characteristics of solid-liquid two-phase mixtures in a flexible hose are investigated using the experiments. Also the performance of the lifting pump for the offshore mining test are estimated. This centrifugal pump with the total head of 55 m is for lifting the minerals on the seabed. The inlet of this pump is connected to the flexible hose, which is attached to the miner collector. The flexible hose is specially manufactured for the use in mining test with 100 mm in diameter. The results show the performance of the lifting pump is good for the offshore test.

근해역 채광시험을 위해 제작된 양광펌프의 성능을 검증하고 곡관을 포함하는 유연관내 고-액 혼합물의 유동특성을 파악하기 위한 고-액 2상류 유동실험을 수행하였다. 총 양정 55 m의 양광펌프는 원심펌프로서 펌프의 상하단에는 유연관이 연결된다. 실험에 사용된 유연관은 해양채광에 적합하도록 직경 100 mm, 단위길이 10 m로 제작되었다. 실험결과 20%의 고체체적점유율까지 양광실험에 무리가 없는 것으로 확인하였으며 기존에 개발된 전산모델의 예측이 실험결과와 유사함을 확인하였다.Introduction
