Abstract

Unsteady modes of gasless combustion in rectangular rods prepared from a mixture of two powdered reagents with an admixture of low-melting inert metal powder were explored by numerical modeling. Rods with square cross section were found to burn in a mode of spinning combustion. The number of spinning hot spots is defined by sample dimensions. On going to the configuration of long plates with the same cross area, a mode of spinning combustion gradually transformed to that of frontal one.

矩形棒中的非定常燃烧模式

摘要

通过数值模拟探索了由两种粉末试剂与低熔点惰性金属粉末混合物制得的矩形棒中无气燃烧的不稳定模式。发现具有正方形横截面的棒以旋转燃烧的方式燃烧。旋转热点的数量由样品尺寸定义。在采用具有相同横截面积的长板构型时，旋转燃烧的模式逐渐转变为额叶燃烧的模式。
