Simulation of smoke movement in a ventilated tunnel by using fine hydrogen bubbles

미세수소기포를 이용한 환기 터널내의 연기거동 모사

The authors previously presented that the experimental technique using fine bubbles generated by electrolysis simulated fire behavior in a tunnel. We improve this experimental setup to enable this to be considered tunnel-ventilation by circulation of salt water. In this paper we introduce the new experimental setup and the visualization of fine hydrogen bubbles simulated smoke in a ventilated tunnel by using a laser sheet are presented.
