Report on the Use of Sidewall Sprinklers and Water Mist Nozzles for Primary Damage Area (Fire) Cooling

摘要

The objective of this test series was to identify and characterize sidewall sprinklers and water mist nozzles that can thermally manage (i.e., prevent flashover and reduce the intensity of the fire) the primary damage area following a missile hit. The key variables that were investigated are: spray characteristics, flow rate, nozzle location, fire size, vent size, perburn time, and compartment configuration (i.e., obstructed vs nonobstructed). The results of the test discussed in this report indicate a potential risk with the low pressure nozzle. This risk is manifested in lower cooling capacity and resulting potential increase in water flow.
