As being the supporter airflow quantity will increase, the back again-layering length considerably decreases (210,000 m3/h < V < 270,000 m3/h). Nonetheless, because the enthusiast movement volume proceeds to enhance (270,000 m3/h < V < three hundred,000 m3/h), the reduction while in the back again-layering length gets to be less pronounced, the smoke distribute length on the latter is just 헬스케어 11% of that of the previous. Hence, picking out acceptable enthusiast airflow volumes and enthusiast inclined angles them can effectively greatly enhance the effectiveness of tunnel smoke extraction programs. In addition, by comparing with regular enthusiasts, we see that mobile admirers present an alternate effective tactic for the duration of firefighting by permitting changes in length in the fire resource and admirer inclination angles, enhancing fire suppression performance although reducing Electricity losses.
