Experiment Study on enhancing performance of the air curtain in subsea tunnels

Vol 59 Issue 3 [ Month 06- Year 2018]

It is difficult to effectively exhaust the smoke from the tunnel because it is typically has semi-closed structural characteristics and moreover, because of rising temperature coupled with toxic smoke, it is difficult to perform evacuation and firefighting activities. In this study, after zoning the area to prevent the smoke from spreading to neighboring area, smoke control performance test by tunnel height was performed using air curtain system which is the local smoke control system that will secure the evacuation passage as well as extend the time for evacuation. Consequently, in case of both the tunnel height 6.3m for ordinary road tunnel and 3.5m for small car, smoke barrier created by air curtain contributed to preventing the hot smoke generated by the vehicle fire in tunnel from spreading to neighboring zone
