Analysis and Optimization of Ventilation Mode of Smoke Control System in Subway Station Fires
In the subway station fires, the most immediate threat to passengers’ life is not the direct exposure to fire, but the smoke inhalation because it contains hot air and toxic gases. Theoretical analysis and CFD simulations are applied to analyze the various possible ventilation model and obtain the optimization of ventilation mode in the subway station fires. According to the structure character...
متن کاملSimulation of Metro Train Fire in an Underground Station of Tehran Metro Line 7
In this research a fire scenario was simulated in one of the stations of the line 7 of Tehran's subway system. The Line 7 is under construction and the ventilation system is under design. Fire was set for a stopping metro train at the platform of the station. A 160 meter length eight-car metro train with the forth wagon on the fire was studied. The heat release rate is based on a quadratic f...
متن کاملA Network Fire Model for the Simulation of Fire Growth and Smoke Spread in Multiple Compartments with Complex Ventilation
There is a need for fire modeling tools capable of rapid simulation of fire growth and smoke spread in multiple compartments with complex ventilation. Currently available tools are not capable of simulation of complex ventilation arrangements in a timely manner. To address this problem, a new fire model called Fire and Smoke SIMulator (FSSIM) has been developed. FSSIM is a network model whose c...
متن کاملThe effect of fire on vegetation diversity indices, a case study: Sirachal research station
Fire affects vegetation and changes plant succession. In this paper, the vegetation of Sirachal Research Station, which burned in the summer of 2014, was studied and compared with the unburnt areas, based on biodiversity indices. The research was implemented as a factorial experiment in a completely randomized design. First, on the basis of physiognomy, the area was divided into three parts: sh...
متن کاملOptimization of Ventilation Mode of Smoke Control System in High-rise Building Fire
In high-rise building fire, a large amount of fresh air will be pressurized into the fire floor when smoke ventilation and prevention system is used. The fresh air dilutes the smoke, but it also reduces the efficiency of mechanical exhaust. The assumption that vertical composition smoke control model (air curtain combined with pressurization and exhaust fan) is put forward. The mathematic model...
