Abstract

Several nations around the world have been concentrating on a survey of another energy resources for exhausting fossil fuel which those are concerned for essential resources necessary for manufacturing hi-tech products. In the present time, these hi-tech and aerospace industrial products are being manufactured aggressively focusing on poly-metallic contents such as Mn, Fe, Co, Ni, Cu, Mo, Li, and etc., which are all contained within the manganese nodules. Today, the highly soaring of gold price is continuously instigating the price of manganese nodules. In order to lift the manganese nodules from the deep seabed, it is necessarily important to steadily check the stable buoyancy state of manganese nodules by following the flow attraction of seawater causing the velocity difference between seawater and nodules. Therefore, it is planned and executed to develop and collect the deep ocean manganese nodules and sooner or later, the actual system will be hopefully operated in deep-sea bed depth for optimized lifting potency of the nodules.

화석연료의 고갈로 인해 대체할 여타 에너지원을 찾기 위한 세계의 여러 국가들은 지구의 자원고갈에 대비한 주요 관심을 갖는 데에 집중해 왔다. 국제적 최첨단 산업의 완성제품에 필수요소로 부속되는 주요 금속은 세계 강대국의 공격적으로 확보해야 할 필수 자원으로 대두되고 있다. 이러한 최첨단 산업 및 우주개발산업에 필수적 부품요소 금속으로 그 중요성이 부각되는 시점에, 심해저에 분포하는 망간단괴의 금속성분이 Mn, Fe, Cu, Co, Ni, Mo, Li 등을 함유하고 있어 개발의 중요성은 최근 금 가치의 폭등과 더불어 주요 금속가의 급격한 상승에 따라 더욱 대두되고 있는 실정이다. 따라서 심해저 망간단괴의 개발 및 채광은 시급한 실정이고 국내에서도 장기개발계획을 시행중에 있고 조만간 고수심 실해역 개발에 착수할 예정이다. 심해저 고수심 양광을 통한 단괴의 수송시, 중요하게 고려해야 할 부분은 해수로 가득찬 양광관내에 초기운전가동시에 해수를 따라 단괴의 안정적 상승여부가 필수적이다. 따라서 금번연구에서는 최적의 유송력으로 단괴의 안정적인 상승여부를 전산실험하여 최소의 적절한 양광 포텐스 특성들을 분석하여 장래에 고수심 실해역에 실가동시 불안정한 문제를 예측할 수 있도록 하였다.
