| 摘 要： | 独头巷道压入式通风的风筒一般布置在独头巷道的侧壁,风筒出口的位置在巷道侧壁的中部,与迎头保持一定的最小距离。根据现场实际情况,同时为了便于分析,通过建立独头巷道受限贴附射流通风物理模型,确定边界条件和网格划分,进行数值计算,得到流场等值线图,表明了贴附射流的形成过程,并对其结果进行分析。

| Abstract: | The heading face forced ventilated wind-sock is commonly disposed in the sidewall of heading face,the wind-sock exit is located at the middle part of laneway sidewall,keeping some least distance to head-on.Therefore,considering the site practical situation and the convenient analysis,aeration physics model of heading face limit attachment jet flow is set up,the borderline condition and network partition is determined and numerical value calculation is conducted,founding out the isoline chart of flow field,w... |
