Elasto-Rotational Instability in Couette-Taylor Flows of Visco-Elastic Fluids

ORAL

Abstract

We discuss the so-called ``elasto-rotational'' instability of visco-elastic polymer fluids in a Couette-Taylor geometry. We study under what conditions (viscosity and relaxation time of the polymer fluid, velocity profile of the Couette-Taylor flow) this instability is analogous to the magnetorotational instability that plays a fundamental role in astrophysical accretion disks.
