巷道通风预测的非定常解析系统的开发

研究开发了一种用于地下通风巷道网络的非定常预测解析系统，解析系统包含了巷道外气候的季节变化及巷道壁的围岩与巷道内气流的热传递关系对预测解析的影响因素。采用差分法计算巷道围岩内的温度分布，在自然通风条件下，使用某隧道口的一年间季节变化的实测数据，对一地下通风巷道网络模型进行了预测解析。解析结果表明，该预测解析系统能时时刻刻同时详细地计算地下通风巷道的风量，温度，湿度等通风参数，解析得到的有关通风参数是合理的。

A Study Transient on Predictive Calculation Method of on Underground Ventilation Network

The authors developed a computer program of transient predictive calculation method on underground ventilation network. The program approximated a field data set of seasonal cyclic changes of air Temperature and humidity at the inlet to the sine curves, and included sensible heat conduction from rock to air current. The temperature of rock around and airway was calculated by finite difference method. The prediction method can be used to calculate the variation of flow rates, temperatures and humidities of air flow in the airways along underground network.
