Influence of Front Instability on the Combustion Initiation in Gas-Free Mixture by Local Hot Point

The initiation of combustion of a large mass of condensed mixture being in local contact with the end of the burning layer was mathematically modelled and experimentally studied. The influence of the instability of stationary combustion front in the igniting layer on the penetration of gasless combustion into large volume was showed. It was revealed that the critical conditions for initiating combustion of large volume are determined by front curvature.

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.
