Research on the Characteristics of the Flow Field under Jet Fan Systems and Pacing Value of Jet Fans in Curvilinear Road Tunnel
When the jet fan ventilation system is adopted in the curvilinear road tunnel, the characteristics of the flow field have a great impact on the ventilation and smoke exhaust in the tunnel on fire. Threedimensional numerical mode by FDS is built to simulate and analysis the characteristics of the flow field at different times and positions after the jet fans are turned on, and the results have some reference value to study the laws of smoke spread and temperature distribution in the curvilinear road tunnel in the future, then the suggestions are mad. on the distance value between jet fans.
