Numerical Simulation on Smoke Control for Extra-Long Tunnel Fires

چکیده
Abstract Based on an actual project in Beijing, this article investigates the effect of smoke control strategies extraction efficiency under different fire source locations point system extra-long tunnels using Airpak software. The results show that when a occurs tunnel, tunnel varies greatly depending location and adoption strategies. Due to suction exhaust shaft fan, relative distance between electric valve entrance is close, which will cause within certain range be plug-holing, seriously affecting system. Smoke beyond range, although not occurring plug-holing also relatively low, by changing opening strategy can effectively improve so as efficiency.

Coupling Simulation on Subway Tunnel Smoke Propagation
Subway is consisted of tunnels, platforms and ventilation shafts. The air flow between these structures forms a ventilation network. There is a need for fire modeling tools capable of both rapid and precise simulation for fire and smoke propagation in such ventilation network. Computational Fluid Dynamics (CFD) is widely used in subway fire performance design. However, the boundary conditions u...

متن کاملSmoke movement for sprinklered fires
This paper presents the initial results of a project initiated by the American Society of Heating, Refrigerating and AirConditioning Engineers (ASHRAE) and the National Research Council of Canada to investigate smoke movement resulting from a sprinklered fire in a communicating space into an adjacent large open area such as an atrium or retail mall. Recent research on the interaction of sprinkl...
متن کاملThe critical ventilation velocity in tunnel fires—a computer simulation
In ventilated tunnel fires, smoke and hot combustion products may form a layer near the ceiling and flow in the direction opposite to the ventilation stream. The existence of this reverse stratified flow has an important bearing on fire fighting and evacuation of underground mine roadways, tunnels and building corridors. In the present study, conducted by the National Institute for Occupational...
متن کاملNumerical simulation of water entry of tunnel cross section with different deadrise angles and tunnel radiuses
This study deals with the numerical modeling of symmetrical water entry of tunneled sections. In this study, firstly, the water entry problem of a wedge section without tunnel in four different deadrise angles was numerically modeled. The obtained results related to the pressure distribution on these sections and the maximum pressure have been compared with the experiment results. In the next s...
