On non-equilibrium thermorheodynamics of the media of variable microstructure

The current study obtains the regularities and analyzes and the influence of the variable of intermolecular orientation and intramolecular relaxation microstructures of the media class and their base flows on the kinematic and dynamic characteristics of the flow. For a medium with a relaxation internal microstructure, the study distinguishes a range of the numbers De and We, in the region of which the dissipative flows are not solely determined by the gradient of the corresponding streaming potential as for a medium with an orientational microstructure, they are solutions of the evolution equation for the internal parameter of the medium. The equation allows for a description of the process of relaxation of thermorheodynamic parameters to their instantaneous and local equilibrium values.
