초록

해양에서 발생하는 원유 유출 사고는 해양 생태계와 연안 환경에 큰 피해를 초래하므로 신속하고 효율적인 방제기술이 요구된다. 기존의 오일펜스, 스키머 및 흡착제는 기상 및 해상 조건에 따라 회수 효율이 저하되는 한계가 있다. 이에 본 연구에서는 해양오염 방제선용 하이드로사이클론 분리기의 최적 설계 방안을 제시하고자 하였다. 입구 질량유량, vortex finder 길이 및 vane의 유무를 설계변수로 선정하여 수치해석을 수행하였으며, 각 조건에서의 오일 분리효율을 비교·평가하였다.

Abstract

Oil-spill accidents in marine environments cause severe damage to marine ecosystems and coastal areas. Consequently, efficient oil-spill response technologies are necessitated. This study performs numerical simulations to optimize the design of a hydrocyclone separator for marine oil-spill response vessels. The effects of inlet mass flow rate, vortex-finder length, and vane installation on oil-separation efficiency are evaluated.
