龍潭中興路住家火災之數值模擬
Numerical Simulation Analysis for the Residential Fire on Jhongsing Rd.,Longtan Township.
摘要
根據歷年火災次數統計資料顯示，台灣地區97年火災發生次數為2,879次，因火災死亡人數101人，其中以住宅火災1,171次占40.67％最多。在台灣建築物消防法規上，對一般透天住宅的火災預防並無強制規定，一旦發生火災，往往會造成人員嚴重傷亡和財物損失。因此為避免或減少類似災害之發生，需要針對火災發生原因做進一步深入的研究與分析。 本研究以龍潭中興路住家火災為研究對象，利用NIST所發展的火災模擬軟體Fire Dynamics Simulator (FDS) 進行火災情境模擬，研究當時火場的上層溫度、一氧化碳濃度、氧氣濃度及氣層高度的分佈變化，探討相關參數對火災的影響，並瞭解相關參數對人員逃生避難時間所造成的影響，以期能做為防火工程設計的參考，來保障人員生命安全，避免更多家庭悲劇的發生。

According to Ministry of the Interior（MOI）Statistical information, there were 101 people dead within 2,879 fire accidents in Taiwan, 2008. Among them, a highest 40.67% of fire accidents (1,177times) caused by the residential fire. According to the building fires’ safety regulations in Taiwan, there is no mandatory requirement for the residential fire prevention in general. When residential fire occurred, it always caused serious personnel casualties and property losses. Therefore, how to avoid or reduce the occurrence of such similar disaster, further researches and analysis of fires are necessary. This paper selects the residential fire case on Jhongsing Rd., Longtan Township as research object. Fire Dynamics Simulator (FDS) developed by NIST has been utilized to simulate fire scenarios, in order to study the changed of upper layer temperature distribution, carbon monoxide concentration, oxygen concentration and gas layer height in fire site as well as the effect of parameters to fire scenarios. The simulation results expected to understand the effect of parameters for person’s refuge time during the fire and provide references for fire protection engineering design, in order to ensure the people’s lives, and avoid more occurring of family tragedies.
