Abstract

The foam monitor is equipment for extinguishing fires, particularly for oil tankers or cargo areas of the carrying vessel. This equipment is installed on the cargo tank deck. Generally, the projection distance is important for designing an extinguishment. On the other hand, the form monitors in current industry have been designed by trial and error rather than by numerical analysis method. Therefore, the shape design of the new form of monitor is needed. In this study, numerical analysis was performed to determine the projection distance prediction, and experiment results were used to make a comparison with the analysis results. The proposed method was applied to the modified form of a newly designed monitor in a company.

폼모니터는 유조선 또는 위험화학품 선적운반선의 화물구역 화재를 진압하기 위해 화물탱크 갑판 상에 필수적으로 설치되어 있는 장치이다. 일반적으로 폼모니터의 주요한 설계 변수는 폼모니터를 통해 분사되는 소방 수의 분사거리이다. 그러나 현재까지 산업계에서는 폼모니터의 분사거리에 대한 수치 해석적 접근 보다는 경험에 근거한 데이터를 바탕으로 설계하고 있다. 따라서 새로운 폼모니터의 형상 설계 시 많은 시간과 비용이 필요한 실정이다. 본 논문에서는 폼모니터의 분사거리 예측에 대한 수치해석적인 방법을 제시하고 제안된 수치 해석 기법의 결과와 실험 데이터를 비교하여 제안된 해석 방법의 효용성을 검증하였다. 또한 설계 변경 된 폼모니터에 대하여 추가적인 수치해석을 통해 설계방안을 모색하였다.
