Research output: Contribution to journalArticle


A thermomechanical model is developed for propagation of steady wave of a chemical reaction in a condensed medium. The stresses and deformations arising in the reaction run, as a result of thermal and 'concentrational' matter expanding, are related by the Maxwell formulas for a viscoelastic medium. The expression for heat flow is taken in the form of the generalized Fourier law with finite relaxation time of the heat flow. It is found that the model admits the existence of two different front propagation regimes (subsonic and supersonic).
