Simulation of different flow regimes in a narrow-gap spherical Couette flow

作者：

Highlights：

• We have used 3D-INSEs to simulate different flow instabilities in spherical Couette flow.

• A narrow-gap clearance ratio β=0.1 have been investigated.

• We have obtained Taylor vortex flow, wavy vortex flow and spiral wavy vortex flow.

• Some new flow regimes found for this narrow-gap clearance ratio.
