Abstract

Propagation of combustion wave in a two-layer system was numerically modelled with account for melting, interdiffusion, and heat losses. Combustion wave propagation in between two reactive layers of a bilayer structure was found capable of steady propagating until some critical bilayer thickness (l_cr). An oscillation combustion mode arising above l_cr was found to yield a product with periodic inhomogeneities in its structure. Strong heat losses led to encapsulation of combustion process into a shell of unreacted mixtures.

在两个反应层之间的燃烧波传播：考虑融化和相互扩散的数学建模

摘要

考虑到熔化，相互扩散和热量损失，对两层系统中燃烧波的传播进行了数值模拟。发现在双层结构的两个反应层之间的燃烧波传播能够稳定地传播直到某些临界双层厚度（l _cr）。以上所产生的振荡燃烧模式升_CR发现，得到的产物与在其结构中周期性的不均匀性。大量的热损失导致燃烧过程封装到未反应混合物的外壳中。
