โœฆ Synopsis

Microscopic boundary layer effects for rough sphere rotation arc considered via a slip boundary condition. Predictions for diffusion constants are compared with molecular dynamics results. The slip coefficient is discussed.

## Angular velocity correlations for rough spheres are examined via a slip boundary condition. This condition approsimateIy accounts for microscopic boundary layer effects and exposes both microscopic and collective decay effects The results compare well with molecular dynamics calculations.

Effective boundary conditions or wall laws are proposed for a laminar flow over a rough wall with periodic roughness elements. These effective conditions are posed on a regularized boundary which allows the details of the wall to be avoided and dramatically reduces the computational cost. The effect
