What is Rheological Chaos?

  • Event date: 22nd October 2001
  • Speaker: Mike Cates (Formerly School of Physics & Astronomy, University of Edinburgh)
  • Location: Room 2511,

Event details

Recent experiments on a variety of viscoelastic fluids reveal cases in which the stress response to a steady shear flow is unsteady, or vice versa. The simplest type of instability gives a spontaneously oscillatory response to steady driving; however, chaotic behaviour has been seen instead in some systems. It remains a theoretical challenge to identify the physical mechanisms for such rheological instabilities and produce minimal models of the oscillatory and/or chaotic regime; one or two first attempts will be outlined.

About Condensed Matter lunchtime seminars

This is a weekly series of informal talks given primarily by members of the soft condensed matter and statistical mechanics groups, but is also open to members of other groups and external visitors. The aim of the series is to promote discussion and learning of various topics at a level suitable to the broad background of the group. Everyone is welcome to attend..
