도로터널내 설치된 젯트팬 승압력의 실험적 연구

Jet fan system is very economic ventilation system. So many jet fans are installed in road tunnel. It is important to clearly grasp their performance for ventilation system design. The experiment was carried out to investigate jet fan pressure rise which is the most important ventilation design factor. Experiments were conducted by using actual jet fans installed in the Yang-Mi-Jae and Jook-Ryoung tunnels. It is found that jet fan pressure rise is suitable for designing ventilation system by comparing the equation value with experiment value based on velocity.
