The second Benelux tests (Lemaire and Kenyon, 2006) examined an open deluge sprinkler system with a flow rate of 12.5 l/min/[m.sup.2] (0.3 gpm/f[t.sup.2]), which was installed in two zones; the fire area and 17.5 m (57.4 ft) downstream of the fire.
Ko (2011) tested a deluge sprinkler system generating large water droplets to investigate the interaction of the water spray and a longitudinal air flow in the range of 0.6-3.0 m/s (2-9.8 ft/s) in a tunnel (10 m wide and 5 m high (32.8 ft wide and 16.4 ft high)).
When the values of source factors, [omega][(V/[V.sub.c]).sup.2]/[Q*.sup.1/2] [greater than or equal to] 9, the smoke backlayering was limited for the deluge sprinkler system tested.
Based on product, the market is segregated into wet sprinkler system, deluge sprinkler system

As an added benefit, the system uses a deluge sprinkler system

* "Deluge sprinkler systems
keep glass cool during a fire." Laboratory tests have shown that the effectiveness of deluge sprinklers depends a great deal on where the fire starts in relationship to the glass, how quickly the sprinklers are activated, and other hard-to-predict occurrences.
