Mesli, B., Quilgars, A., Chauveau, C. and Gokalp, I., 2000. Extinction Limits Of Opposed Jet Turbulent Premixed Methane Air Flames With Water Mist. Fire Safety Science 6: 445-456. doi:10.3801/IAFSS.FSS.6-445
An experimental study on water mist extinction of turbulent premixed flames is described. The aim of the study is to compare the extinction limits of opposed jet turbulent methane/air flames with and without the addition of water mist. and to study the influence of several parameters including the structure of water mist in terms of droplet s i x and mass fraction of the condensed phase, mean strain rate, equivalence ratio and turbulence. An existing opposed jet turbulent premixed flame experimental set-up is modified to include a water mist production system. An air assisted atomizer is developed to produce and control the water mist. The structure of the water mist is characterized by a Phase Doppler Anemometer. Water mist interaction with three different configurations of opposed jet premixed flames is explored and the results arc discussed by introducing a parameter representing the water mist efficiency.
