Abstract

Any slight tilt or tide on the fluid in a rotating cylinder causes periodic motions, whose radiation pressures in the viscous boundary layers force mean differential rotations of the fluid, which are found numerically. At certain fluid depths, even very small tilts can cause shears large enough for perturbations to overcome Ekman friction, causing turbulence. An experiment confirms the theory.
