摘要
Using the conservation law, the theories of high temperature gas dynamics, fluid mechanics, the physical and mathematical turbulence flow field model is set up to simulate the tunnel fire and its smoke flow. An experimental fire in a tunnel is studied in light of the turbulent flow model. The results indicate that the turbulent flow field model is better than before and has prettily good consistency with the experimental data. Through the numerical simulation analysis, it is concluded that the fully developed smoke flow downstream can clearly present the distribution of layered temperature, concentration of CO2 downwind and smoke flow velocity.
