Scientific paper

We report in detail a visco-elastic instability from experimental observations and numerical simulations of a Couette-Taylor flow of a polymer fluid in a narrow gap between two rotating concentric cylinders with a Kepelerian-like velocity profile, where the angular velocity decreases radially outward while the specific angular momentum increases radially outward. Under the considered parameters, the inertial Rayleigh instability and the purely elastic instability are not possible. It is proposed that this observed instability is analogous to the magnetorotational instability which plays a fundamental role in astrophysical Keplerian accretion discs.
