Autoturbulization of gas flames: Theoretical treatment

Along with the classical treatment of hydrodynamic instability, the various technical approaches to the problem of autoturbulization of spherical prop agation of flame in gas mixtures involves the treatment of the development of the combustion surface into a fractal structure. The most likely scenari o of autoturbulization and emergence of an experimentally observed limiting self-similar mode of turbulent combustion consists in the development of t urbulence on a large scale due to Taylor instability. In so doing, the init ial acceleration of flame, the rate of dissipation of turbulent energy, and its spectral boundary are defined by combustion. The energy balance of tur bulence assumes in this case a steady-state behavior, and the fractal chara cteristics of free autoturbulized spherical flame correlate with the fracta l characteristics of flames in turbulent flow.
