摘要

摘要对供体-受体系统燃烧的空间模式进行了数值模拟。燃烧波的离散性由单元格尺寸决定。计算了取决于单位立方晶胞尺寸的样品燃烧速度。结果表明，随着单位立方晶胞尺寸的增大，样品的平均燃烧速度也随之增大，这是因为晶胞接触边界的比面积减小了。研究还发现了具有离散结构的平行六面体样品的单热点自旋燃烧模式。

Spatial Gasless Combustion Modes in a Sample with Discrete Structure

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.
