چکیده انگلیسی
Computational Fluid Dynamics (CFD) is a useful tool in tunnel fire safety, providing reliable data as a supplement and extension of experiments. In this work, simulations of reduced-scale tunnel fire experiments, concerning in a concrete tunnel model with a scale of 1/3, are presented. It mainly focuses on evaluating the quality of the CFD results. The results show that the simulations consist with the experiments with natural ventilation and longitudinal ventilation. Extension tests are also presented, considering the length and the working pressure of the water mist zone under longitudinal ventilation. It concludes that the downstream temperatures decrease with the length of water mist zone, and no pronouncedly change is obtained as water pressure increases under longitudinal ventilation.
