Numerical Simulations on the Extinguishing Effect of Water Mist System with Different Parameters of Longitudinal Ventilation in Curve Tunnel Fire

Figure 5

Variation of temperature at different heights in curvature 1/500 and 1/860 tunnels under different longitudinal ventilation speeds. (a) Variation of vault temperature in curvature 1/500 tunnel under different longitudinal ventilation speeds and variation of vault temperature in curvature 1/860 tunnel under different longitudinal ventilation speeds. (b) Variation of eye height temperature in curvature 1/500 tunnel under different longitudinal ventilation speeds and variation of eye height temperature in curvature 1/860 tunnel under different longitudinal ventilation speeds.
