Abstract

The deep-sea hydraulic pump was designed for the pilot lifting test(PLT) after the determination of lifting distance and flow quantity. We deduced four design factors for the optimization of the hydraulic design. Four design factors are inlet/outlet angles of one blade of an impeller and inlet/outlet angles of one blade of a guided vane. Each angle has three variation of magnitude to be called three levels. For the respective factors, three levels of factors were deduced on the basis of CFD. The optimum values of four angles were determined by using design of experiments and parametric study.

본 연구에서는 PLT를 위한 심해역 양광펌프의 설계를 위해 양정과 유량을 결정한 후 수력설계를 수행하였다. 수력설계의 최적화를 위하여 4개의 설계인자를 추출하였다. 4개의 설계인자는 임펠라의 입구각도, 출구각도 그리고 가이드 베인의 입구각도, 출구각도이다. 각 각도는 3수준이라 불리우는 3개의 각도크기 변화가 있다. 이렇게 추출된 설계인자를 바탕으로 각각의 인자에 대하여 3수준의 인자를 정한 후 CFD 해석을 바탕으로 최적의 인자를 도출하였다. 네 개의 각도에 대한 최적값은 실험계획법과 파라메트릭 연구를 통하여 결정하였다.
