MODELING THE MIXING OF COHESIONLESS MATERIALS WHEN THE FLOW OF GRANULAR MEDIUM OCCURS WITH PLASTIC SHEAR DEFORMATIONS

摘要

The mechanism responsible for interaction between inelastic spherical homogeneous particles during shearing of a granular medium subject to plastic deformation is analyzed; based on this analysis, a method is proposed for prediction of the coefficient of quasi-diffusion mixing as a function of particle size and flow characteristics. The kinetics of particle mixing when materials are subject to plastic shear deformations are investigated by methods of physical and mathematical modeling; these investigations suggest the adequacy of the computational function proposed for determination of the coefficient of quasi-diffusion mixing.
