pre-flame1914
1914 Proc. Royal Soc. A. 90 279 It is during the ‘preflame’ period of ignition which precedes the true explosion that water vapour influences the rate of propagation.
1973 Boldt & Griffiths in J. P. Allinson Criteria for Quality of Petroleum Products v. 59 Amongst the main preflame products are the highly temperature sensitive peroxides and if these exceed a certain critical threshold concentration, the end gas will spontaneously ignite before the arrival of the flame front emanating from the sparking plug: this causes detonation or ‘knocking’.
1996 Jrnl. Fluid Mech. 318 1 Oscillations imposed at the nozzle exits result in reactant concentration and temperature oscillations at the outer edge of the preflame diffusive zones.
