Abstract

Numerical study on a lifting system developed for shallow sea test is performed by a CFD model. In this study, the flow behaviors in a lifting pump and flexible hoses is simulated by using FLUENT, a commercial CFD model. Two cases for calculation the pump cavitation behavior are selected according to the hose length and the depth of lifting pump. From the numerical results, it is found that the vortex flow is observed in the first-stage stator and the calculated NPSH meets the minimum required by a lifting pump based on the shallow sea environments.

천해 양광시험을 위해 개발된 양광시스템에 대한 수치 해석이 CFD 모델에 의해 수행되었다. 본 연구에서 양광펌프와 유연관의 유체유동은 FLUENT, 즉 상용화된 CFD모델을 이용하여 모사하였다. 펌프공동현상의 계산을 위해 유연관 길이와 펌프 수심의 두가지 경우가 선택되었다. 수치결과로부터, 볼텍스 유동이 첫단의 스테이터에서 관측되었고 계산된 NPSH는 양광펌프의 공동을 방지하기 위해 최소한으로 요구하는 조건을 만족시키는 것으로 예측되었다.
