Velocity Field in an Elongational Polymer Solution Flow

Abstract

The experimental evidence has shown that the presence of polymer molecules in a fluid flow has an influence on its characteristics. It becomes more and more clear that a phenomenon, like friction reduction, can be related either to the energy storage abilities of the molecules or to the existence of an extensional viscosity. But, until now, the conditions of extension of the molecules are poorly understood.
