Existing research into this topic primarily focuses on low-altitude areas, neglecting the impact of extreme environmental conditions such as low temperature, oxygen level, and pressure in high-altitude regions. Based smoke diffusion theory, a series CFD numerical simulations were conducted order to investigate characteristics highway tunnel at high altitude. The results indicated that increase altitude would enhance longitudinal propagation velocity smoke, leading more pronounced CO...
In the existing research on tunnel fires, researchers primarily focus straight tunnels, neglecting impact of curved sidewalls in tunnels. Based theory smoke diffusion, a series CFD numerical simulations was conducted using Fire Dynamics Simulator to investigate characteristics distribution highway tunnel. The results indicated that distinct were observed when fire occurred compared with those significant differences particularly evident for radius curvature below 1000 m. By comparing from...
In previous studies on tunnel fires, researchers primarily focus the impact of a single factor smoke dispersion characteristics in tunnels, neglecting combined effects multiple influencing factors and their mutual interactions. Based theory dispersion, series numerical simulations were performed using fire dynamics simulator to reveal distribution mountain spiral highway tunnels. The results indicated that radius curvature, altitude, slope gradient predominantly govern Specifically,...
