FDS in electric cable tunnel fire application

Abstract：In order to gain the cable tunnel conflagration parameter, distribution condition of tunnel inner air dampness and conflagration smoke fog thickness following time, space is studied.The fluid moves (Fire Dynamics Simulator) calculation flow mechanics software FDS, which mainly to simulate a marriage partner in the conflagration is built by using USA national standard and development of the technology research institute (NIST) .The conflagration carries out the full-size simulation on industry cable tunnel.Through the data handling simulating and experiment analysis, change law smoke thickness and oxygen thickness and longitudinal temperature of cigarette is given when the cable tunnel conflagration happened, It provids the theory basis of a fire rescue escape in the conflagration.
