| description | Taking Majiazhai double highway tunnel as a prototype, the mathematical model of double tunnel fire is established to analyze smoke plume spread and diffusion during air flow organization process of highway tunnel fire. In the conditions of double tunnel fire jet fans closed, tunnel jet fans open, ventilators of tunnel and cross-road open simultaneously, the temperature field, pressure field and concentration field of air flow and smoke relative motion are obtained. Then it puts forward that the key technology for smoke countercurrent control in double tunnel fire is to increase the ventilation resistance in fire source upwind cross-road and reduce the air quantity flowing from tunnel jet fans into cross-road. |
