摘要: 基于独头巷道的特点和有限空间的受限贴附射流理论,建立了独头巷道压入式受限贴附射流通风降温的数学模型。采用Fluent软件对入风流在巷道内速度场的分布及在不同风速下巷道内的温度场的分布进行数值模拟。结果表明在风速为5m/s,送风温度为25 ℃时,较好的改善了巷道内的热环境。

Abstract: Based on the characteristic of heading face and the theory of restrained wall-attached jet ventilation in confined space, the mathematical model of pressed ventilation and temperature drop in heading face is set up. Using the Fluent simulate and analyze the distribution of the inlet airflow and temperature field under different airflow speed in roadway. The result shows that inlet airflow with 5m/s speed and 25 ℃ can reach the comfortable work environment.
