Coupling of transport and thermodynamic properties of nonideal multicomponent matter

The general relations between thermophysical properties of non-ideal matter are investigated to check the approximations for the calculation of the pr operties in the linear response case. In particular for the examination of the approach which is proposed for the full set of the transport coefficien ts, determining currents of pulse, heat, mass and charge in high energy den sity matter with strong interparticle interactions and chemical reactions. To do this the detailed analysis has been carried out of available experime ntal data of non-ideal matter transport coefficients of various substances. The effective transport coefficients (these coefficients first of all coup le the thermodynamic and transport properties of a non-ideal matter) are in troduced, relating the mass currents of chemical elements and the convectiv e heat current to temperature and element concentrations gradients and the effective fields in a matter. The number of conditions imposed on the nonli near, nondiagonal matrix of the effective transport coefficients and on the high derivative coefficients matrix of the set of conservation equations f or a non-ideal medium are derived The properties of these matrixes are the next result of coupling of transport and thermodynamic properties of a matt er. It is considered also the relations between transport and thermodynamic properties of matter in the case of a nonlinear response. At last the coup ling is studied for a system under the plasma phase transition within the f ramework of Cahn-Hilliard approach.
