摘要/Abstract

摘要： 为研究巷道壁面均匀潮湿和局部潮湿对围岩及巷道壁温度影响差异,准确预测潮湿巷道风流温湿度,根据三维围岩温度场理论,建立围岩热传导、风流温度和湿度数值计算模型,数值模拟巷道壁面均匀潮湿模型(UWSM)和条带潮湿模型(PWSM),探讨不同参数条件对巷道风流温湿度影响。结果表明:三维热传导模型在局部潮湿巷道计算得出围岩温度及风流温度分布更贴合实际;提出根据潮湿率确定潮湿度修正系数的方法,可提高大型通风网络温湿度预测计算精度。

Abstract: In order to study different influences caused by uniform wet surface and partly wet surface on temperature of surrounding rocks and roadway walls and to accurately predict airflow temperature and humidity in wet roadway, a numerical calculation model for heat conduction of surrounding rocks and airflow temperature and humidity was constructed based on theory of three dimensional temperature field. Then, uniform wet surface model (UWSM) and PWSM were simulated, and influences of parameters on airflow temperature and humidity were discussed under different simulation conditions. The results show that rock and airflow temperature distribution calculated by three dimensional heat conduction model under partly wet condition are more reasonable. The proposed method of determining correction factors of wetness based on wet area-ratio can improve prediction accuracy of temperature and humidity in large-scale ventilation networks.

Key words: wet roadway, airflow temperature and humidity, partly wet surface model (PWSM), numerical simulation, wet area-ratio
