Abstract

A discrete 2D model of combustion process in donor–acceptor mixture consisting of activated and non-activated reaction cells was proposed. The influence of the activated composition fraction and cell size on the burning velocity of a combined mixture was analyzed. Calculations showed that an increase in the activated composition fraction elevates the average burning velocity. It was found that burning velocity vs cell size dependence passes through a maximum.

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.
