Surface curvature and secondary vortices in steady dense shallow granular flows
C. Gadal, C. G. Johnson, J. M. N. T. Gray
Dense granular flows exhibit both surface deformation and secondary flows due to the presence of normal stress differences. Yet, a complete mathematical modelling of these two feat…
