Here we show that this matrix is intrinsically diagonal when the driving forces are chosen from the gradients of potentials that drive the fluxes of their ...
In thermodynamics, the Onsager reciprocal relations express the equality of certain ratios between flows and forces in thermodynamic systems out of equilibrium, but where a notion of local equilibrium exists. "Reciprocal relations" occur between different pairs of forces and flows in a variety of physical … Ver mais The fundamental equation The basic thermodynamic potential is internal energy. In a simple fluid system, neglecting the effects of viscosity the fundamental thermodynamic equation is written: Ver mais Let $${\displaystyle x_{1},x_{2},\ldots ,x_{n}}$$ denote fluctuations from equilibrium values in several thermodynamic quantities, and let $${\displaystyle S(x_{1},x_{2},\ldots ,x_{n})}$$ be the entropy.

Web1.1 Onsager’s reciprocity relations In his two seminal papers in 1931, Lars Onsager showed how time-reversibility of a system implies certain symmetry properties of macroscopic observables of the system (Ons31; OM53).
