Abstract
A series of full-scale fire tests of water mist systems in an engine mock-up enclosure was carried out by the National Research Council of Canada. During the tests, two water mist discharge modes (continuous and cycling) were employed. The test results showed that the use of cycling discharge improved the efficacy of water mist in fire suppression, with a shorter extinguishment time and less water requirement. The improvement of the efficacy of water mist in fire suppression using cycling discharges was attributed to the faster depletion rate of oxygen in the compartment and the recurrent dynamic mixing created by cycling discharge.
