The diffusion of perturbations is investigated, beginning with Onsager-type equations for particle current and energy flow and conservation equations. This method takes into consideration the interplay of density and temperature, and the phenomena produced by this interplay - often neglected with other approaches - are fully accounted for. Time evolution of density and temperature profiles are presented. The speed of propagation of perturbation is calculated. © 2002 Elsevier Science B.V. All rights reserved.

Abstract
The diffusion of perturbations is investigated, beginning with Onsager-type equations for particle current and energy flow and conservation equations. This method takes into consideration the interplay of density and temperature, and the phenomena produced by this interplay - often neglected with other approaches - are fully accounted for. Time evolution of density and temperature profiles are presented. The speed of propagation of perturbation is calculated. © 2002 Elsevier Science B.V. All rights reserved.File in questo prodotto:
