Numerical Simulation of Fire Suppression in Stilted Wooden Buildings with Fine Water Mist Based on FDS

In this paper, to reflect a real fire combustion situation of stilted buildings with typical wooden structure, we used FDS numerical simulation software study the suppression effect fine-water-mist fire-extinguishing system under different working conditions. The influences mist droplet diameters, spray flows, and nozzle densities on temperature change in area were analyzed compared. particle sizes fog droplets exhibited significant impact, indicating that smaller size, faster vaporization rate better cooling effect. was when size 150 μm or less compared 200 300 μm. As flow density increased, field decreased, enhanced, optimal at water-mist 8 L/min. Therefore, given possible conditions, should be high, while suitable selected achieve best
