The Three-Dimensional Flow Past a Rapidly Rotating Circular Cylinder

Abstract

The high Reynolds number (Re) flow past a rapidly rotating circular cylinder is investigated. The rotation rate of the cylinder is allowed to vary (slightly) along the axis of the cylinder, thereby provoking three-dimensional flow disturbances, which are shown to involve relatively massive (O(Re)) velocity perturbations to the flow away from the cylinder surface. Additionally, three integral conditions, analogous to the single condition determine in two dimensions by Batchelor (1), are derived, based on the condition of periodicity in the azimuthal direction.
