The instabilities of fluid flows between coaxial differentially rotating cones are considered in the limit of the small gap approximation as function of the cone angle. As in the experimental study of Wimmer (presented at the 10th International Couette-Taylor Workshop, Paris, 15–17 July 1997), a transition from Taylor vortex instabilities to Ekman-type instabilities is found at a cone angle of about 45°.
