根据独头巷道受限贴附射流规律,基于独头巷道受限贴附射流特征参数计算,分析风筒出口直径与流场的关系、风筒出口风速与射流轴心速度变化的关系等,得出独头巷道受限贴附射流特征参数对流场有影响较大,各项特征参数与流场关系的研究使得对独头巷道的通风环境监控更加有利。从而达到改善此类工况的作业环境并提高此类工况的安全系数。
Based on the law of confined jets attached to single-headed tunnel, the relationship between the outlet diameter of the duct and the flow field is analyzed based on the characteristic parameters of the confined jet attached to the single-headed tunnel. The relationship between the wind speed at the exit of the duct and the jet axial velocity is obtained The characteristic parameters of confined jet attached to a single laneway have a great influence on the flow field. The study of the relationship between the characteristic parameters and the flow field makes the monitoring of the ventilation environment of a single headway more favorable. So as to achieve a better operating environment for such conditions and improve the safety factor for such conditions.
