Segregation model development holds promise for translation of academic research into industrial practice. One significant hindrance to model development, however, is the inherent difficulty in measuring segregation rates (especially in an experimental setting). In this project, we seek to establish an “equilibrium” between segregation and flow perturbation in free surface granular flows in order to overcome this experimental hurdle. That is, by using periodic flow inversions, we hope to alter the steady-state distribution of particles whereby there exists a balance between...
