Abstract:
A nonstationary mathematical model of thermal propagation of flame in a layered heterogeneous system is proposed. The structure and dynamics of the frontal exothermal transformation in quasihomogeneous, transitional, and relay-race regimes are studied. Averaged characteristics of the front and dynamics of transformation of individual elements of a “discrete” combustion wave are analyzed using the model proposed. A correlation is established between the combustion of a model medium and real heterogeneous compositions. It is shown that the maximum combustion velocity is reached at an intermediate level of medium dispersion in a transitional parametric region.
Keywords:
combustion waves, heterogeneous systems, multilayered nonstationary regimes, modeling.
