Microscopic boundary layer effects and rough sphere rotation

摘要: A calculation of the rough sphere angular velocity correlation function is presented which takes into account presence both microscopic boundary layer and outer hydrodynamic regions around test particle. The region approximately accounted for by slip condition while generalized equations (frequency dependent transport coefficients plus fluid spin variables) are used to describe region. approximate coefficient use processes occurring in discussed context kinetic theory results. Since a description incorporated, present contains collective effects. structure result compared some detail recent renormalized on same system various levels approximation examined. results good agreement with molecular dynamics c...
