潮湿巷道热环境2-D和3-D模型数值模拟及比较

2-D and 3-D model of the Wet roadway thermal environment numerical simulation and comparison

介绍了2-D和3-D模型的建立和异步差分法解析过程,模拟了潮湿巷道风流和围岩的热交换过程,并分析了影响热湿交换的因素及巷道壁面水分和风流之间的热湿交换关系。利用3-D模型,数值模拟井下作业环境,预测井下环境动态信息,对开展深井降温、降湿技术和矿井空调技术的研究,具有指导作用。

This article introduced 2-D and 3-D model,also introduced asynchronous finite difference process method,and simulated the wet roadway and the surrounding air flow heat exchange process,analyzed the exchange of heat of moisture and air flow between the tunnel wetness wall and the hot water Wet exchange relations factors.On the basis of the 3-D model,using Numerical simulation Underground environment and predict Dynamic information.It guided the Deep mine cooling Technology dehumidified Technology,and Mine Air Conditioning Technology Research.
