Theoretical Prediction and Numerical Simulation Research of the Length of Smoke Regressing in Longitudinally Ventilated Tunnels

摘要：

Smoke spreading and controlled in tunnels has become one of the advanced subjects of the research in tunnel fire. The theoretical prediction model of the length of smoke regressing in tunnel fire is established combining some conclusion and theoretical formulas of predecessors in this field. A highway tunnel modeJ of 500 meters length is sets up by Fire Dynamics Simulator, 10 groups of different tunnel fire case are simulated using longitudinal ventilation. The correctness and effectiveness of the theoretical prediction model about the length of smoke regressing have been verified through analyzing and comparing with the numerical simulation results.
