报告摘要:Heat conduction is investigated on three levels: equilibrium, Fourier, and Cattaneo. The Fourier level is either the point of departure for investigating the approach to equilibrium or the final stage in the investigation of the approach from the Cattaneo level. Both investigations bring to the Fourier level an entropy and a thermodynamics. In the absence of external and internal inuences preventing the approach to equilibrium the entropy that arises in the latter investigation is the production of the classical entropy that arises in the former investigation. If the approach to equilibrium is prevented, then the entropy that arises in the investigation of the approach from the Cattaneo level to the Fourier level still brings to the Fourier level the entropy and the thermodynamics even if the classical entropy and the classical thermodynamics is absent. We also note that vanishing total entropy production as a characterization of equilibrium state is insufficient.

讲座人介绍

Miroslav Grmela is the Professor of the Department of Chemical Engineering at Ecole Polytechnique of Montreal. His major research interests include geometrical structures of mesoscopic dynamics, thermodynamics and transport processes. Results are applied to molecular simulations, modeling of thermodynamic and rheological properties of polymeric fluids, suspensions and immiscible blends, and non-Fickian diffusion in polymers. He had published more than 200 publications. Since 1975, Professor Grmela has been receiving Discovery Grant from the Natural Sciences and Engineering Research Council of Canada, and received Prize Grant from the Natural Sciences and Engineering Research Council of Canada in 2014. From 2016 to now, he worked as a visiting professor in Zhou Pei-Yuan Center for Applied Mathematics at Tsinghua University.
