Abstract
Spatial modes of combustion of the donor–acceptor system were numerically modelled. The discrete character of the combustion wave was determined by the unit cell size. The burning velocity of the sample depending on the unit cubic cell size was calculated. It was shown that as unit cell size grows, the average burning velocity of the sample increases, which is explained by a decrease in the specific area of the cell contact boundaries. Single-hot point spin modes of combustion of the parallelepiped sample with a discrete structure were found.
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.
