PROPAGATION OF TEMPERATURE WAVES IN MEDIUM WITH INTERNAL THERMAL RELAXATION

Research output: Contribution to journalArticle

Abstract

In this article the wave solutions of heat transfer equations, for classical model and for two alternative non-stationary models (hyperbolic and model with a time delay) have been studied. Modeling of temperature impulse propagation was performed according to dispersion relations obtained from heat transfer equations. It was shown that propagation of temperature impulse in non-stationary models could significantly differ from temperature diffusion in classical model. This can be used for signal transmission and that temperature waves could be used for delay line construction. Keywords: wave heat transfer, non-stationer models of heat transfer, temperature impulse propagation, undumped temperature waves, dispersion of temperature waves.
