摘 要: 通风控制下的建筑物火灾具有很大危害性。对受通风控制的建筑物通道内的火灾烟气运动进行了数值模拟,给出了烟气温度、速度和组分质量分数的分布。将模拟结果与燃料控制下通道内火灾烟气运动的计算结果进行了对比,揭示了不同燃烧状况下通道内烟气运动与火蔓延的特点。 Building fires occurring under ventilation-controlled conditions are extremely hazardous. A numerical simulation of the fire smoke flow in a building corridor under ventilation-controlled conditions is presented. The distributions of gas temperature, velocity, and species mass fractions are obtained. The results are compared with those calculated under fuel-controlled conditions. The features of smoke flow and fire spread are delineated under different combustion conditions.
