Numerical Simulation of Highway Tunnel Fire under Semi-Transverse Ventilation

LIANG Yuan,FENG Lian(College of Mechanical Engineering,Southwest Jiaotong University,Chengdu 610031,China)  
Computer Fluid Dynamics(CFD) is employed to simulate the Highway tunnel fire under the semi-transverse ventilation.According to the velocity field analysis and temperature field with different ceiling tuyere distances and opening tuyere numbers,the effects of these different schemes are evaluated.Comparing these schemes,it is shown that 15 meters ceiling tuyere distance and 4~5 opening tuyeres ventilation scheme with 3m/s longitudinal ventilation velocity can give satisfactory effect.
