Numerical analysis on flue effect in tunnel fire based on FDS

LIANG Ping1,WEI Liang-yi1,LONG Xin-feng2(1.Powering Engineering Department of Electric Power College,South China University ofTechnology,Guangzhou 510640,China;2.Key Laboratory of Enhanced Heat Transfer andEnergy Conservation of the Ministry of Education,School of Chemistry and ChemicalEngineering,South China University of Technology,Guangzhou 510640,China)  
By means of a CFD simulative analytical method,FDS(Fire Dynamic Simulator version4.0) is adopted to analyze the temperature field distribution in tunnel fire without flue and with flue.The result shows that when a flue is set up,the temperatures of positions downstream,upstream and above the fire are much lower.
