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.
