Abstract

The use of the retarded motion expansion as a constitutive equation has long been known to be valid only for small Deborah number flow. We demonstrate that ‘solution’ which cannot be obtained as a regular perturbation about the Newtonian solution is physically meaningless. This is discussed in connection with a recent paper in this journal.
