矿井火灾烟气蔓延特性的多维混合模拟研究

Multidimensional Mixed Simulation Study on Smoke Propagation Features of Mine Fire

  • 摘要: 采用多维混合模拟技术对巷道火灾进行模拟,具有耗时短、精度高等优点。矿井火灾的多维混合模拟结果表明,一维模拟会高估火灾时巷道的温度,而多维混合模拟与一维模拟相比对风流参数的变化更加敏感,能够对火场风速、温度等参数的变化进行快速响应,因而模拟结果更加准确。
    Abstract: Using multiscale modeling technique to simulate the mine fire has the features of short time-consuming and high precision. The simulating results indicated that one-dimensional modeling could overestimate the temperature of fire. Multiscale modeling is more sensitive than one-dimensional modeling in variation of airflow parameter, which can give a more rapid response to the change of temperature or air velocity. Thus the simulation results are more accurate.
