화재시뮬레이션을 이용한 터널 내 화재시 제연설비 필요성 검토
A Study on the necessity of smoke control system in the tunnel fire using fire simulation
초록
In this study, fire simualtion was performed to examine the necessity of smoke control system in the tunnel fire. The heat release rate was set to 5 MW and 20MW, and the visibility was measured at 1.8 m, which is the breathing limit, when there is no jet fan. Through this, it was confirmed that 5 MW did not affect the visibility even without the jet fan, and in the case of 20 MW, a jet fan was required to secure the visibility. The visibility was measured at the same location by installing the jet fan, and the simulation was performed by reducing the design volume flow rate of 8.5 m3/s by 80% and 50%, respectively. As a result, it was confirmed that sufficient visibility was secured when the design flow rate and 80% were reduced.
