摘要:
为探究风筒位置对掘进巷道风流分布规律的影响，利用Fluent软件确定出实验模型内流体进入“第二自模区”的临界风速，保证实验模型与实际巷道的流动相似，采用粒子图像测速仪（PIV）对压、抽风筒距迎头不同距离下的前压后抽式通风流场进行测量。实验结果表明：抽风筒距巷道迎头距离的改变对迎头处流场影响较小，涡流中心位置也不会发生改变，当抽风筒距迎头距离大于4.5S，回流区的风流充分发展，流动较为平缓。压风筒距巷道迎头距离的改变对迎头处流场和涡流影响较大，当压风筒距迎头距离大于3S，涡流中心位置向远离迎头的方向移动，涡流区域逐渐扩大。基于相似理论的PIV实验结果可为矿井掘进巷道通风工作提供一定参考。
Abstract:
In order to explore the influence of air duct position on the wind flow distribution law of the excavation roadway,the Fluent software was used to determine the critical wind speed of the fluid entering the second self-mode zone in the experimental model to ensure that the experimental model was similar to the flow in the actual roadway,and the particle image velocimetry (PIV) was used to measure the front pressing and rear pumping wind flow field under different distances between the pressing and pumping air ducts and the head.The experimental results showed that the change of the distance between the pumping air duct and the roadway head had little influence on the flow field at the head,and the position of the vortex center would not change.When the distance between the pumping air duct and the roadway head was greater than 4.5S,the wind flow in the recirculation zone was fully developed and the flow was relatively gentle.The change of the distance between the pressing air duct and the roadway head had greater influence on the flow field and eddy current at the roadway head.When the distance between the pressing air duct and the roadway head was greater than 3S,the eddy current center moved away from the roadway head,and the eddy current region gradually expanded.The PIV experimental results based on the similarity theory can provide a certain reference for the ventilation work of excavation roadway in the mines.
