Abstract

The now field of a fluid being called ''the third order fluid'' or the ''fluid of grade three'' is considered for a non-Newtonian now in the vicinity of a plane wall, suddenly set in motion. The velocity field of the flow is described by a fourth order, non-linear partial differential equation. The solution of this differential equation shows that for short time a strong non-Newtonian effect is present in the velocity field. However, for long time the velocity field becomes a Newtonian one.
