矿井火灾巷道烟气流动场模型

ESTABLISHMENT OF FIELD MODELS FOR SMOKE FLOW IN A FIRE ROAD DURING MINE FIRE

矿井火灾时期，火源巷道内高温烟流运动为三维非定常的流动及传热传质过程。从化学流体力学基本方程组出发，在一定简化与假设条件下，建立了进行火源巷道烟气流动计算机模拟研究的场模型，给出了模型求解的初始及边界条件，简要介绍了模型的求解方法，并结合工程实例。

The movement of high temperature smoke in a fire road during mine fire was a three dimensional unsteady flow which is accompanied with heat and mass transfer. Under given conditions of simpification and hypothesis, the a author established the field model for computer simulation of smoke movement in fire road using fundamental equations of chemical fluid mechanics, gave initial and boundary conditions for solving the model and described briefly its algorithm.
