针对目前矿用空气幕隔断巷道风流的特点和结构设计的要求,通过对单机循环型空气幕流动模型理论分析得到空气幕控制风流的主要影响因素。进一步运用相似原理,建立空气幕隔断巷道风流实验的模型,通过实验得出该巷道空气幕的最优角度为30°和最佳供风器出口宽度为8 cm。最后,利用FLUENT进行数值模拟计算,来验证实验结果的正确性。本研究结果对矿用空气幕隔断巷道风流的结构设计具有重要的理论指导作用。
Aiming at the characteristics and structural design requirements of the current mine air curtain partition airflow, the main influencing factors of air curtain control airflow are obtained through theoretical analysis of the flow model of the single air circulation curtain. Based on the principle of similarity, the model of the airflow experiment of partitioned roadway with air curtain is established. The optimum angle of air curtain is 30 ° and the width of outlet of the air supply is 8 cm. Finally, FLUENT is used to carry out numerical simulation to verify the correctness of the experimental results. The results of this study have important theoretical guidance on the structural design of mine air curtain partition airflow.
