Linear phenomenological laws

Description

Linear phenomenological laws are at the core of the thermodynamics of irreversible processes TIP, considered to apply generally near equilibrium but more generally in transport processes (e.g. Fick's law). In TIP, linearity is discussed as the dependence of generalized flows on generalized forces. This paradigm is challenged by the ergodynamic concept of fundamentally non-linear isomorphic flow-force relations and is replaced by the generalized isomorphic flow-pressure relations. Flows I [MU·s-1] and forces F [J·MU-1] are conjugated pairs, the product of which yields power I·F = P [J·s-1 = W]. Then vectoral and vectorial transport processes present inherently non-linear flow-force relationships, not different from scalar chemical reactions.
