| Abstract: | Summary We present experimental results of fluid flow instabilities between different rotating surfaces. We start withcounter-rotating Taylor vortices between two coaxial cylinders. We go over to rotating cones with increasing apex angle. Due to the growing cross-flow we finally end up with spiral vortices allrotating in the same direction between a rotating disk and a housing. Figure 13 gives a complete survey of these results. We discuss the transition from one vortex system to the other in detail.Dedicated to Prof. Dr. Dr. h. c. mult. S.
