선박 화재진압용 분사장치의 형상 변수에 따른 성능 분석

Abstract

In this study, the spray performance was analyzed by carrying out the experimental and numerical analyses of a deck foam system which is an important component of the vessel fire suppression foam system. In the fire occurrence, the deck foam monitor, which is installed at regular intervals on the deck, sprays fire extinguishing fluid into the fire area to suppress the fire. For responding to the fire accidents, it is necessary to include a suitable spray distance and sufficient injection flow rate of foam which is made in foam station. In the flow analysis, variables consist of X1 to X4. The effect of X1 (length between bodies) to spray distance is small. When X2 (guide distance) and X3 (turbulence breaker distance) increase, spray distance is increased. Furthermore, the increase of X4 (nozzle-guide distance) tends to reduce the spray distance. Based on the analysis results of the four variables, a new model was designed to analyze and the results of this simulation confirmed that the spray distance was 70.7 m and the flow rate was 6165 l/min. The results of this study are expected to be available as basic data for basic design, characteristics and performance verification of similar fire extinguishing and spray equipment.
