Abstract

Three dimensional two phase numerical analysis was performed to understand the flow characteristics of solid-liquid mixtures in lifting pipes and to enhance the performance of the lifting pump for the mining tests at the offshore areas. The analysis deduced an optimum inlet area design through pump performance estimation where numerical analysis comparison was conducted for two models which have different inlet shapes according to the change of time. The Eulerian method was used to consider the movement and inter-phase transfer between flow and particles. As a result, the optimum inlet shape was determined by analyzing flow patterns in the lift pump and the total pressure difference between the inlet and outlet of the lift pump.

심해저 양광시스템의 핵심부품인 양광펌프의 최적설계를 위해 3차원 고체-액체 2상 유동에 대한 전산해석을 수행하였다. 비정상상태 전산해석을 통해 두 가지 형태의 펌프의 입구부 형상에 대한 분석을 수행하였다. 고체입자와 해수의 상호작용과 유동해석을 위해 오일러리안 해석기법을 적용하였다. 그 결과 펌프 내부의 망간 유동경향분석과 입출구부분의 망간체적점유율, 전압차 등의 분석결과를 산출하였고 이를 통하여 양광펌프의 입구부 형상을 결정할 수 있었다.
