METHOD OF RELAXATION MOMENTS FOR STUDYING NONLINEAR LOCALLY NONEQUILIBRIUM PROCESSES OF TRANSFER OF POLYMERIC SYSTEMS

A method for simulating the processes of transfer of thermodynamic systems with polymeric microstructure is considered. The method is based on the classical locally equilibrium medium-state entropy concept expanded by the introduction of a structural tensor parameter whose evolution characterizes the nonlinear anisotropic relaxation properties of a thermodynamic system and the associated transfer phenomena. The dynamic, thermal, and mass transfer characteristics of macrotransfer are determined by corresponding integrals of relaxation moments.
