FDS(Fire Dynamics Simulator)를 이용한 전동차 화재감지 시뮬레이션

초록

Fire detector shall be equipped within a confined area which may lead to risk of fire in accordance with the Technical Specifications for Urban Railway Vehicles (KTRS-VE-Part51). As per this technical guidelines, heat and smoke detector are considered generally to the vehicle design to perceive the fire occurring at the condition of pre-determined temperature (65℃) and smoke concentration (15%/m). In considering fire detection design, parameters such as amount of detectors and its arrangement deemed to be main factors could affect on detecting promptness. The aim of this study is to review the parameter adequacy for fire detection design by simulating the fire growth and detection time for the typical urban railway vehicle by using of FDS (Fire Dynamics Simulator)
