Assuming linear relations between the thermodynamic fluxes and the thermodynamic forces, in this Chapter we apply Onsager's reciprocal relations to determine the most general symmetry conditions that are satisfied by the phenomenological coefficients. Then, these conditions are applied to particular cases, obtaining the constitutive relations of pure fluids, multicomponent mixtures, metals and non-isotropic media. Finally,at the end, we see how these same symmetry conditions can be applied to find the cross correlation properties of the fluctuating thermodynamic fluxes.

Abstract
Assuming linear relations between the thermodynamic fluxes and the thermodynamic forces, in this Chapter we apply Onsager's reciprocal relations to determine the most general symmetry conditions that are satisfied by the phenomenological coefficients. Then, these conditions are applied to particular cases, obtaining the constitutive relations of pure fluids, multicomponent mixtures, metals and non-isotropic media. Finally,at the end, we see how these same symmetry conditions can be applied to find the cross correlation properties of the fluctuating thermodynamic fluxes.File in questo prodotto:
