โœฆ Synopsis

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.

In the past decade, the lattice-Boltzmann method (LBM) has emerged as a very useful tool in studies for the direct-numerical simulation of particulate flows. The accuracy and robustness of the LBM have been demonstrated by many researchers; however, there are several numerical problems that have not
