The traditional and Burnett models of heat and mass transfer were considered in a two elements medium with spatial heat production which is proportional to concentration of one of the elements. Investigation of the models was provided using computational multi-parameter nonlinear analysis and analytical methods. Characteristics of thermal regimes of the models were studied and compared. Results of thermal regimes modeling can be used, for example, in modern energetic apparatuses development. (C) 2013 Elsevier Ltd. All rights reserved.
