Steady-state thermodynamics of shearing viscoelastic fluids

A/Professor Peter Daivis
RMIT University

Date

4-5 p.m., Thursday, 10 February, 2005

Location

School of Physics Common Room
Room 64 Old Main Building
The University of New South Wales

Outline

In the first part of this talk, I will discuss the recent development of a thermodynamic description of shearing viscoelastic fluids that is exact for linear viscoelasticity. Molecular simulation results aimed at the verification of a Maxwell relation that is postulated for thermodynamic properties in a non-equilibrium shearing steady state will be discussed, and an interesting relationship between the first normal stress coefficient and the relaxation modulus will be described.

In the second part, I will make several more speculative comments on the possible extension of this theory to shearing non-linear viscoelastic fluids, and discuss some of the requirements that such a theory must
satisfy.

The audience, including graduate students, are invited to meet the speaker 15 minutes beforehand over wine and cheese in the Physics Common Room.
