Models of SHS: An overview
2007
International audience; The theoretical models of SHS based on lamellar or cellular approximations of the heterogeneous reactive media are comparatively analyzed. It is shown that the ratio of the reaction time to the characteristic time of heat transfer between particles is a decisive parameter for the combustion wave propagation. When the time of reaction is shorter than the time of heat exchange, the combustion occurs in a discrete mode; in the opposite case, a quasi-homogeneous combustion mode occurs. Development of the discrete cellular model does not discard the quasi-homogeneous approach but markedly extends the scope of combustion theory. This extension enables explanation of many o…
Macrokinetics of combustion in heterogeneous media: comparative analysis of homogeneous, layered and cellular models
2007
Experimental data on intrinsic features of the combustion wave propagation in heterogeneous reactive mixtures published during last decade have initiated development of several novel theoretical models of the process. In this paper these models are overviewed, analyzed and compared. The analysis shows that ratio of the characteristic reaction time to the time of heat transfer between particles of the mixture is a key parameter for the mode of combustion wave propagation. When the reaction time is much smaller than the time of heat exchange, the combustion occurs in so-called discrete mode; in the opposite case quasi-homogeneous combustion mode takes place. It is emphasized that the developm…
