Passive explosion suppression by blast-induced atomisation from water containers

摘要: Abstract The experimental findings of a combined wind tunnel and field-scale explosion study blast-induced water release its effect on blast suppression are reported. water, subsequent atomisation, from containers both with open partly enclosed surfaces, was first studied in tunnel. An array were then placed at differing positions the ignition point, together flame acceleration obstacle arrays fixed positions, inside 5.1 m long by 0.3 m2 cross-section duct. droplet size minimum speed necessary for container to suppress found depend upon number their shape size. One particular extinguished when any position beyond 1.7 m point. When extinction observed internal over-pressure substantially reduced external completely eliminated. This suggests new approach toward passive suppression.
