Theory of non-equilibrium electrical surface phenomena in
concentrated disperse systems. 1

Shilov V. N., Zharkikh N. I., Borkovskaya Yu. B.

Application of the method of thermodynamics of irreversble processes to the cellular model of a concentrated dispersion

By using the apparatus of non-equilibrium thermodynamics, one has formulated the cellular method for considering the phenomena of transfer in concentrated disperse systems. Within the framework of this method, one has equally taken into consideration all the non-equilibrium processes (e. g. viscous, diffusion, and electrical ones) and derived expressions for integral (i. е., the observable ones) thermodynamic fluxes and forces through local fields. The suggested method guarantees the accurate fulfillment of the Smolukhovsky formula for electroosmosis when used for any hydrodynamic cellular model (those of Kuvabara, Happel, or Mehta).
