Validity of the Onsager reciprocal relations
This article examines the conditions under which the Onsager reciprocal relations hold for the matrix of transport coefficients in the constitutive laws for heat and mass transport in continuous systems. For a K component system and a suitable choice of reference frame, those laws may be expressed in the form vector J/sub i/ = summation from j = 0 to K (H/sub ij/vector F/sub j/) summation from j = 0 to K (H/sub ij/grad h/sub i/ where vector J/sub 0/ is the energy flux, vector J/sub i/ for i = 1,. . .,K is the mass flux of the i/sup th/ species, and the vector F/sub j/ = grad h/sub j/ are thermodynamic driving forces in which the h/sub j/ are potentials that are functions of the local thermodynamic state; and H/sub ij/, also functions of the local state, are the transport coefficients whose symmetry is under consideration. All terms in Equation 1 will depend in general on position.
