Flow fields between differently shaped bodies of revolution are studied. These bodies are rotating cones with different apex angles, cylinder-cone combinations, disks as well as oblate and prolate ellipsoids. The basic flow are fully three-dimensional and influence the occurring instabilities. The dependence of the occurrence and the development of Taylor vortices, Görtler vortices and cross-flow instabilities on the described geometries are discussed. By separating the influence of the dynamics and the geometry on the vortices the effect of both parameters can be studied separately. Due to the simultaneous existence of sub- and supercritical flows the development at the threshold can be studied very clearly. Furthermore, the rich variety of occuring flow patterns - often existing side by side - offers new insides in unstable flows. A possible transition from counter-rotating Taylor vortices to unidirectional-rotating cross-flow instabilities is described. The influence of the governing parameters, like acceleration, gap width etc. are discussed.
