Abstract:
The effect of the diameter and height of the reaction volume on combustion of mixtures of CrO$_3$/Cr$_2$O$_3$/C/Al и CrO$_3$/Cr$_2$O$_3$/B$_2$O$_3$/Al was studied. The limits of gravity separation with regard to the height and diameter of the metal and oxide phases in the molten combustion products were determined. To explain the results, we propose a qualitative model of the process in which the liquid-phase state of the medium in the combustion front and behind the combustion front determines the characteristics of the processes taking place in the systems studied.
Keywords:
scale factor, combustion front, burning velocity, diameter of reaction volume, combustion temperature, high-calorific mixtures, melt, phase separation, plugs.
