Stability of a traveling roll system in a rotating disk flow
L Schouveiler, P Le Gal, MP Chauve - Physics of Fluids, 1998 - pubs.aip.org
The stability of a traveling roll system, which results from the development of a primary
instability of the flow between a stationary and a rotating disk, is experimentally studied. The
characteristics of this traveling pattern and of the bifurcation from which it results are
obtained. We show in particular that the band of the stable roll modes is limited by the
Eckhaus secondary instability.
