  • This paper investigated the fire and smoke behavior in the compounded multiplex theater using FDS with various spacial and boundary conditions to ensure the fire safety of the multiplex. The results showed that more rapid temperature increase and smoke can be induced near the exit door for the lower fire load duo to the horizontal smoke movement. The overuse of fire resistants can generate more smoke while delaying combustion rate, which can give adverse effect to the evacuation. The mal-function of the exhaust fan would obstruct smoke exhaust but also retard the function of sprinkler head.

  • This paper aims to simulate by FDS(Fire Dynamics Simulator) the distributions of temperature and smoke on fires in accommodations on boards. The paper focuses on analysis of temperature at fire occurrence and soot density. The purpose of this study is to predict the possibility of safe escape and efficient fire extinguishing method using fire simulation results.

  • Smoke is recognized as the major killer in fire situation. smoke often migrate to building locations remote the fire space, threatening life and elevator shafts frequently become smoke-logged, there by blocking evacuation and inhibiting rescue and fire fighting. It is the aim of this study to investigate and analyze the research trends of smoke movement in Fire.

  • The authors previously presented that the experimental technique using fine bubbles generated by electrolysis simulated fire behavior in a tunnel. We improve this experimental setup to enable this to be considered tunnel-ventilation by circulation of salt water. In this paper we introduce the new experimental setup and the visualization of fine hydrogen bubbles simulated smoke in a ventilated tunnel by using a laser sheet are presented.

  • 산업 발전과 인구의 급격한 증가에 따라 건축물은 고층화 및 인텔리젼트화 되어가면서, 화재로 인한 인적·물적 손실은 계속적으로 증가하고 있다. 따라서 과거보다 구체적이고 근본적인 대책의 마련이 필요하게 되었다. 현재의 소방시설의 설계는 사양중심(Prescriptive Based)의 체계로 되어 있다. 우리나라의 경우는 사양중심 체계로 되어있으나 외국에서의 공학적 도구와 연구를 바탕으로 하는 성능위주의 방화설계에 대한 연구가 시작되어 기존에 개발된 화재거동과 연기이동 및 피난의 소프트웨어를 이용하여 소방대상물의 열 분포, 연기이동, 피난특성, 발생열량 및 내화도 등을 분석함으로써 적합한 방화설계가 진행중이다.(중략)

  • In this paper, the comparison on the fire driven smoke flow for platform types was conducted in the Deeply Underground Subway Station. Soongsil-University station (47m depth) as a bank type platform and Mandeok Station as a island type platform were selected for fire numerical simulation. The characteristics of fire driven smoke-flows were analyzed from the simulation results. The proper plan of evacuation against fire for each type was considered through the results.
