It applies to systems near equilibrium when the properties of interest have even parity, and assuming that the fluxes and their corresponding forces are independent. An exception occurs with magnetic fields in which case there is a sign difference Mjj = -Mjj [141].
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.
