Synchronization in Turbulent Spherical Couette Flow Subject to Nonuniform Rotation

Abstract

The paper presents the results of numerical study of turbulent flows of viscous incompressible fluid in a rotating spherical layer in the presence of synchronization. The synchronization of the turbulent flow occurs under the action of periodic variation of the inner sphere rotation speed; the angular velocity of the outer sphere is constant. Comparison with the experiment is conducted, and the range of modulation amplitudes is determined where synchronization is accompanied by chaos–chaos type intermittency.
