SELF-SIMILAR BREAKUP OF NON-NEWTONIAN LIQUID JETS

We review similarity solutions to describe the asymptotics of the approach to breakup in non-Newtonian liquid jets. Both creeping flow and flow with inertia are considered for a variety of constitutive models. New phenomena in some models of non-Newtonian flows include the possibility of a jet breaking up simultaneously over a finite length, as well as a purely elastic breakup mechanism in which surface tension plays no role.
