THERMODYNAMIC BASIS FOR CHARGED-PARTICLES TRANSPORT IN VISCOELASTIC FLUIDS

A calculation for the generalized longitudinal stress modulus and elec tric conductivity in an ionic-viscoelastic medium is presented. The sy stem is described within the framework of extended irreversible thermo dynamics in terms of the regular conserved variables and of an additio nal set of independent variables consisting of the stress tensor, its trace, and the electric flux. Using the standard procedure, we derive the time evolution equations for the additional variables. These equat ions are used to obtain general wave vector and frequency dependent ex pressions for measurable properties of the system. We obtain for the l inear case results that have not been derived previously in the litera ture. (C) 1997 American Institute of Physics.
