Abstract

We outline the derivation of conditions that determine the slip velocity and flux of fluctuation energy for collisional flows of frictional spheres at bumpy, frictional boundaries with either cylindrical or spherical bumps. We illustrate their use by solving for the profiles of fluctuation velocity, mean velocity, and volume fraction in steady, fully developed shearing flows between boundaries with frictional, cylindrical features.
