摘要：

Dissipation, the power due to the shear stress at the wall and the boundary layer thickness corresponding to the Rayleigh-Stokes problem for a second grade fluid are calculated for three different motions. In each case, for alpha(1) -> 0, these quantities are going to those for a Newtonian fluid. The changing of the kinetic energy with time as well as some comparisons with results proceeding from Teipel's solution are also presented. (C) 2006 Elsevier Ltd. All rights reserved.
