Calculation of Bulk Materials Mixing Process

The process of mixing of a diffusing powdery material adjoining an absorbing wall moving in a specific manner is investigated. An entropy method based on statistical approach to the mixing process modeling problem is used as the mathematical apparatus. Given the statistical nature of the investigated phenomenon, an expression based on the postulates of the probability theory is obtained for the key process efficiency parameter (inhomogeneity coefficient) as a function of the parameters of this process. A method for determining the macrodiffusion coefficient that characterizes the particles mixing process intensity is proposed.
