Free Surface Velocity Measures of Granular Flows Using MRI at New Mexico Resonance

We find, consistent with surface measurements of the free surface velocity in the horizontal drum, that as the rotation rate is increased the symmetric profile becomes skewed toward the downstream end of the flow. This is due to particles accelerating beyond the midpoint at higher rotation rates before beginning to slow down due to the endwall.
