摘要
建立了一种描述矿井火灾时期火源巷道内烟气流动及传热传质过程的场模型，用ＳＩＭＰＬＥ算法进行模型求解，编制了计算机程序．用模型计算的结果与煤炭科学研究总院抚顺分院火灾实验结果进行比较，验证了模拟计算的正确性．用该模型研究了火灾巷道内火源强度、巷道坡度及风速条件对火灾烟气流动的影响．
A field model for movement of smoke in roadways with fire sources and for heat and mass conductivity was set up.The model was solved by SIMPLE algorithm,and the computer programs were writen.The calculated data from this model were compared with the test data from Fushun Branch of Central Coal Mining Research Institute,which were proved to be correct.The influence of intensity of fire sources,gradient of roadways and air velocity on the movement of smoke in a mine fire was investigated by the model.
