dc.description.abstractShear-induced migration is the diffusion of particles in a direction normal to the flow of suspension. The particles migrate towards the low-shear stress region from the higher-shear stress region. In the kinetic theory of granular flow, the driving potential for the migration of particles is the difference in granular temperature, defined as the kinetic energy of particle fluctuations. The effect of bulk volume fraction on the particle migration in a dense suspension flow through a rectangular microchannel is analyzed. The multiphase simulation was conducted using the multi-fluid volume-of-fluid and granular temperature model. The results show a blunted velocity profile, reduced peak velocity, and an increase in variation of local volume fraction with an increase in bulk volume fraction. © 2023 Wiley-VCH GmbH.
