Soot is perhaps the most harmful element in vehicle tunnels fire as smoke moves harmonize
with the way passengers flee. It decreases visibility and can cause suffocation fatalities.
This paper presents an empirical analysis on the effect of removing smoke through different
ventilation systems on smoke distribution inside the vehicle tunnel, such as water mist system
with transverse ventilation with several extractions of exhaust fans Sustainable human
conditions were also tested. FDS 2019 ver. was used to predict temperature, visibility, and
concentration of co.
Motivation/Background: Present work to investigate the effect of extracting the smoke by
different system of ventilation on smoke spread inside the vehicular tunnel.
Method: By FDS 2019 that used governing equations and naver-stocks equations.
Results: We predicted in this paper smoke spread, temperature distribution, co concentration
distribution and visibility.
Conclusions: This study looks at the importance of smoke control generally as well as the smoke
control criteria in the automotive tunnel configuration which acknowledged them.
Because the smoke barrier water mist screen with a transverse ventilation device improves the
smoke removal technique. FDS is a valuable method for simulating smoke diffusion as well as
other effects |
