为了研究煤田露头火区温度场的分布变化规律,利用Fluent软件对火区进行数值模拟,得到了火区温度场的分布情况。对火区火风压的计算进行了分析,计算得到了火风压值。通过改变边界条件得到了火区温度对露头火区漏风流场的影响:火区高温给气体渗流提供了动力,火区温度越高气体渗流速度越快。
In order to study the variation of temperature distribution in coal outcrop fire area, the distribution of fire field temperature field was obtained by numerical simulation of fire area using Fluent software. The calculation of fire pressure in fire area is analyzed, and the value of fire pressure is calculated. By changing the boundary conditions, the effect of fire zone temperature on the leakage flow field in outcrop fire zone is obtained. The high temperature in the fire zone provides the impetus to the gas seepage. The higher the temperature in the fire zone, the faster the gas seepage velocity.
