摘要 主烟道横截面积一定时,采用数值模拟方法模拟并分析了热压对12层住宅厨房等截面排烟道系统排烟能力的影响.结果表明:随着室内外温差的增大,热压的积极作用更明显,主烟道出口处排烟能力更高,主烟道内压力分布更趋向均匀. If the cross-sectional area of the main flue is certain,numerical simulation methods are used to simulate and analyze the effect of thermal pressure on the central exhaust system of a 12-storey residential building. The results indicate that,with indoor and outdoor temperature difference increasing,the thermal pressure plays a more active role,and the fume exhausting ability of the outlet of the main flue becomes higher,and the static pressure inside the main flue becomes more balanced.
