초록

지구 환경오염문제가 대두되면서 세계 각국에서는 환경오염을 최소화하려는 움직임이 활발히 이루어지고 있다. 국제해사기구(IMO)에서는 해양 대기오염의 상당량이 선박에서 배출되는 배기가스에 의한 것으로 판단하고 있다. 이에 따라서 선진국을 중심으로 선박관련 환경규제 및 선박배기가스 배출기준이 점차적으로 강화되어 가고 있으며, 관련 기술개발이 급격하게 이뤄지고 있다. 본 연구에서는 연료유 스크러버에 사용되는 노즐개발 및 분사노즐의 위치 선정을 위해 실험용 스크러버에서 PIV 실험을 통하여 노즐의 분사속도는 20.1 m/s, 분사각은 $66^{\circ}$을 확인을 하였다. 또한, CFD 해석을 통해 실험값과 비교 하였으며, 이 노즐을 실증 모델 스크러버 사이즈에 적용하여 스크러버에 고르게 분사시키기 위하여 여러 케이스를 적용하여 CFD해석을 진행하여 노즐의 위치를 선정 하였다.

Global warming has recently become an issue that has resulted in a growing trend to minimize environmental pollution. The International Maritime Organization (IMO) has shown that the majority of marine atmospheric pollution occurs as a result of emissions from marine vessels. Therefore, the environmental regulations and emission standards regarding marine vessels have gradually become stricter, and the research and development in this area is experiencing significant progress. In this study, a nozzle for a fuel oil scrubber was investigated using computational fluid dynamics (CFD) and particle imaging velocimetry (PIV). Experiments were conducted on scaled-down model of the scrubber to determine its performance, which was then compared with CFD results. Based on the experimental results, it was found that at a spray angle of $66^{\circ}$, the spray velocity at the nozzle was 20.1 m/s. From this comparison, a full-scale scrubber model was analyzed using CFD, and the effect of the positioning of the nozzle was studied.
