The effect of rotational shear on granular discharge rates

The mass flow rate of a packed granular column subject to rotational shear discharging though an aperture is investigated computationally. We show that the flow rate increases in response to the applied shear. This increase obeys a power-law relation based on the rotational Froude number, Fr = L ω 2...
