| Abstract: | The characteristics of tunnel fire are analysed,the numerical simulation of an engineering example is made with the use of commercial CFD software PHOENICS 3.5 through the application of field modeling method.The spreading rules and characteristics of concentration field and thermal temperature field of the tunnel fire given by the different ventilation speeds are studied,which may provide the theoretical background for evacuation design in tunnel fire.The effective measures of fire rescue and people's evacuation are also put forward. |
| Keywords: | tunnel fire smoke flow numerical simulation concentration field temperature field |
