Global stability analysis of gasless flames propagating in a cylindrical sample of energetic material: Influence of radiative heat-losses

Global linear stability analysis of such flames is performed. It is demonstrated that an increase in heat-losses promotes the flame instabilities for values of the Zel'dovich number lower than in the cases with the heat-losses neglected. The results of the stability analysis are successfully compared with the results of direct three-dimensional calculations showing oscillatory and spinning propagation of the gasless combustion waves.
