Abstract:

The theoretical model describing the sedimentation process, i.e. diffusion induced by the gravity (centrifugal) field in multicomponent system is presented. This procedure starts from the combined mass conservation law, equation of motion, volume continuity equation and Nernst-Planck flux formulae. Two dimensional calculations of sedimentation process in InPb system are presented. Example applications of this theory applied to binary system is evidence of sedimentation in condensed matter via diffusion mechanisms. Keywords: sedimentation, interdiffusion, gravity, pressure, thermodynamics, volume continuity.
