Abstract
The numerical simulation method is used to analyze the influence of a unit cell size on the burning rate of a donor-acceptor system. The cell size determines the fragmentation of a combustion wave. It is determined during calculations that, with an increase in the unit cell size, the average burning rate of the sample decreases. The combustion limits of a cellular system with external heat removal from the sample surface are determined: an increase in the unit cell size contributes to expansion of the combustion limits of the sample. The principal possibility of the synthesis in a chemical furnace for the cellular formation of the structure of the reacting system is shown.
