Summary

The laminar turbulent transition in a spherical gap starts with time depending shear waves. The structure of these secondary instabilities is visualized. The dynamical behaviour is investigated by the power spectra of the local wall shear stress at the outer sphere. Depending upon the initial and boundary conditions we get different bifurcations of the laminar-turbulent transition.
