摘要
通过传热学和热平衡原理建立火灾时期火区下风侧巷道烟流温度场方程;利用矿井巷道火灾模拟实验系统测定火灾时期火区下风侧各测点的烟流温度、密度和速度值,得出距离火区下风侧x米处烟流温度变化的实验值,同时通过温度场方程得出烟流温度变化的计算值,得出烟流温度变化的计算值与实验值变化趋势基本一致的结论。实验验证了温度场方程的可行性。
The temperature field equation of fire smoke flow in leeward tunnel is established through heat transfer and heat balance principle; the temperature, density and velocity values of fire smoke flow of every measuring point in leeward tunnel are measured by using the fire simulation system in mine roadway. The experimental value of temperature variation in the leeward x m from fire area is obtained, and at the same time the calculation value of temperature variation can be gotten through the temperature field equation. It is found that the calculation value of temperature changes consistent with the experimental data. The feasibility of temperature field equation is finally verified by the experimental results.
