A. Abstract.
The premixed flame (the self-sustained wave of exothermic chemical reaction) is the most
natural mode of gaseous combustion and, hence, the main object of interest in combustion
theory.
The objective of the present research is to understand and quantify the basic physical
mechanisms occurring in combustion systems involving premixed gas flames and relate the
acquired information to practical situations (e.g. spark-ignition engines, gas-fired burners,
accidental air-fuel explosions).
Specifically, our research efforts were focused on the formulation of mathematical mod-
els for the observed novel phenomena associated with (1) effects of turbulence on burner
stabilized flames, (2) transition to detonation in burner stabilized flames, (3) stability of
counterflow stabilized flames, (4) self-fragmentation in near-limit flames, (5) chaotic dy-
namics in premixed flames, and (6) the effect of stirring on the limits of thermal explosion.
The studies of combustion fundamentals of the type addressed in this project broaden
the conceptual base of the pertinent engineering design fields and may be instrumental in
finding new options of enhancing energy saving and production, determination of safe op-
erating conditions and the reduction of pollution in the urban and industrial environment.2
