title = "Kinetic theory analysis of flow-induced particle diffusion and thermal conduction in granular material flows",

abstract = "The present study on granular material flows develops analytical relations for the flow-induced particle diffusivity and thermal conductivity based on the kinetic theory of dense gases. The kinetic theory modeling assumes that the particles are smooth, identical and nearly-elastic spheres, and that the binary collisions between the particles are isotropically distributed throughout the flow. The particle diffusivity and effective thermal conductivity are found to increase with the square-root of the granular temperature, a term that quantifies the kinetic energy of the flow. The theoretical particle diffusivity is used to predict diffusion in a granular-flow mixing layer, and to qualitatively compare with recent experimental measurements. The analytical expression for the effective thermal conductivity is used to define an apparent Prandtl number of a simple-shear flow; this result is also compared with experimental measurements. The differences between the predictions and the measurements suggest limitations in applying kinetic theory concepts to actual granular material flows.",
