矿井通风网络非稳定风流反风数值模拟

摘要

该文设计了矿井通风网络非稳定数值模拟程序，介绍了程序模块。编制相应的非稳定通风模拟软件，根据雷诺数对局部阻力系数的影响关系修正通风阻力计算模型，最后基于国内某矿对主要风门开启后通风网络反风分支分析，基本满足非稳定流动规律。%Numeric simulation program modules of non - steady flow in mine ventilation network is designed. Preparation of the corresponding simulation software, correct ventilation resistance relationship based on the Reynolds number on the local drag coefficient calculation model. Finally, according to the air reversing branch of a coal mine on the main throttle open ventilation network analysis to meet the basic non - steady flow rule.
