Numerical Investigation on Tunnel Fire Smoke Flow
Using the conservation law, the theories of high temperature gas dynamics, fluid mechanics, the physical and mathematical turbulence flow fields models were set up to numerically simulate the tunnel fire and its smoke movement. An experimental fire in a tunnel was simulated with the turbulent flow model. The simulated results by FLUENT software indicate that the turbulent flow field model in this paper are better and have good consistency with the experimental results. 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 the situation of velocity development.
