Spinning combustion regimes in gasless systems containing one melting component

Abstract

The propagation of a gasless combustion wave in a continuous cylindrical sample pressed from a mixture of solid reactants has been numerically simulated with allowance made for the melting of one of the components. The melting point of the component has been assumed to be equal to the reaction rate “cutoff” temperature. Symmetric and asymmetric combustion regimes can take place in the sample, depending on the sample radius. The reaction rate cutoff temperature is an additional perturbation factor in the propagation of the gasless combustion wave.
