Abstract
An inhomogeneous model of gas-free combustion of a mixture consisting of activated and non-activated cells was proposed. The structure of the combustion wave was studied to suit the scale of heterogeneity, reaction cell size. The influence of gas dispersed layers separating the reaction cells on the burning velocity of a combined mixture was analyzed. The burning velocity dependences at varying effective porosity, effective thermal conductivity, and external heat transfer parameters were constructed.
期刊介绍：
International Journal of Self-Propagating High-Temperature Synthesis is an international journal covering a wide range of topics concerned with self-propagating high-temperature synthesis (SHS), the process for the production of advanced materials based on solid-state combustion utilizing internally generated chemical energy. Subjects range from the fundamentals of SHS processes, chemistry and technology of SHS products and advanced materials to problems concerned with related fields, such as the kinetics and thermodynamics of high-temperature chemical reactions, combustion theory, macroscopic kinetics of nonisothermic processes, etc. The journal is intended to provide a wide-ranging exchange of research results and a better understanding of developmental and innovative trends in SHS science and applications.
