Abstract

When a fire occurs on a naval vessel, rapid suppression and control are essential to mitigate potential human and material losses. Due to the nature of naval vessels, the risk of fuel fires is significant, making the use of aqueous film-forming foam (AFFF) crucial for effective fire suppression. Additionally, the possibility of fires occurring within compartments on the vessel must also be considered. Understanding the trajectory and application range of AFFF in such environments is vital, necessitating the design of firefighting systems tailored to compartmental conditions. In this study, an analysis was conducted to investigate the feasibility of applying spray height and angle for AFFF using computational fluid dynamics (CFD) methodology as a validation tool. Based on these findings, CFD analysis results applicable to compartment environments on naval vessels were obtained. These results will serve as the foundation for the development of firefighting systems capable of promptly responding to fuel fires within naval vessel compartments.

해군 함정에서 화재가 발생하면 잠재적인 인적, 물적 손실을 완화하기 위해 신속한 진압과 통제가 필수적이다. 해군 함정의 특성상 유류화재 발생 가능성이 크며 이에 유류화재 대응에 탁월한 수성막포(AFFF)를 사용하는 것이 화재 진압에 매우 중요하다. 또한 함정의 격실 내에서 화재가 발생하는 상황 역시 고려해야 한다. 이러한 상황에서 수성막포의 궤적과 적용 범위를 이해하는 것이 중요하므로 격실 환경에 맞는 소화 시스템 설계가 반드시 필요하다. 본 연구에서는 수성막포에 대한 전산유체역학 (CFD) 방법론을 검증하기 위한 해석으로 분사 높이 및 각도에 대한 적용 가능성을 조사하였다. 이러한 내용을 바탕으로 하여 함정 격실에 적용가능한 CFD 해석 결과를 얻었다. 이 결과는 해군 함정 격실 내 유류 화재에 신속하게 대응할 수 있는 소화 시스템 개발의 기반이 될 것이다.
