UNDERSTANDING OF THE PHENOMENA OF TEMPERATURE FLUCTUATION ON THE BURNING SURFACE AT THE EVAPORATED ENERGETIC MATERIALS TRANSIENT COMBUSTION
Extensive experimental data independently obtained by various authors and for various kinds of evaporated energetic materials (EM) shows the same - on the burning surface are formed the cellular micro-structures. This phenomenon was a subject of many investigations already more than four decades, however within framework of combustion classical theory the mechanism of its excitation and development does not find an adequate explanation. Detailed analysis and mutual comparison of investigations executed in this area and also detailed analysis of experimental data, obtained in adjacent areas of science and engineering has allowed suggesting the new mechanism of occurrence of this phenomenon. This concept connected, mainly, with excitation of synergetic dissipative spatial-periodic micro-structures (SPMS) in the thin liquid-viscous layer (LVL) and on the EM burning surface and determining the burning wave spatial instability. Obviously, it is possible to speak about the fundamental law determining the processes of the EM burning: the phenomenon of the SPMS formation has universal nature. Suggested concept opens possibility for understanding the phenomenon of local fluctuations of physic-chemical parameters in the EM burning wave. In particular, the process of the SPMS formation on the burning surface provides influence on the temperature distribution in the LVL and on oscillations of the burning surface.
