Spin-up Flows in a Rotating Cylindrical Container
RESUMO
A brief review is made of more recent studies of spin-up flows in a cylinder. The major points of the classical models of spin-up, dealing with the transient process of fluid adjustment to the change in the rotation rate of the container, are discussed. The specific topics that are covered here include the spin-up of a homogeneous fluid from rest, transient flow of a stratified fluid from a state of rest, and transient deformation of the free surface of a liquid in an abruptly rotating cylinder. Assessments are made of the various flow models that have been proposed, and comparisons are made among the analytical predictions, numerical computations, and experimental data. The fundamental dynamic interplay of the Ekman boundary layer and the inviscid interior is stressed.
