Possibilities of surface reaction coupling with transport phenomena

1977

International audience; The thermodynamic approach of nonequilibrium phenomena allows, through the construction of entropy production, appropriate fluxes generalized forces to be identified, and the possibility of coupling to be detected. For the interface phase the expression entropy production consists of two parts: one for irreversible phenomena in the surface (chemical reactions and transport); and the second for transport processes between volumic phases due to the discontinuity of intensive surface parameters. Accordingly in the linear range, the phenomenological relations establishing the thermodynamic coupling between fluxes and forces of the same tensorial order may cause couplings…

Caractéristiques des réactions endothermiques d'interface

1981

The knowledge of the different thermodynamic states of an evaporative interface leads us to propose a formulation of the evolution laws (evaporation rate vs pressure) adapted to each regime (interfacial equilibrium or non equilibrium). Starting from fluid dynamics and irreversible thermodynamics, the model is able to determine the interface flux-forces relations which express the transport coefficients and the thermodynamic coupling effects. The theoretical results are compared to experimental data relative to water evaporation al T =313 K. Taking into account the different regimes arising for the deviation from equilibrium, the model reproduces quantitatively the experimental kinetic curve…

Caractéristiques des réactions endothermiques d'interface. Recherche des états thermodynamiques d'interface en relation avec les écarts à l'équilibre…

1981

International audience; L'endothermicité de la vaporisation peut donner des propriétés particulières à l'interface. L'exploration de la carte thermique du système associée à un modèle permet d'accéder aux profils thermiques dans chaque phase et d'établir les températures à l'interface; ses différents états thermodynamiques sont en relation avec l'écart à l'équilibre du système : équilibre interfacial près de l'équilibre, puis apparition d'une discontinuité de température, enfin déséquilibre de température et de potentiel chimique.
