Spin-Up of a Stratified Fluid in a Cylinder Rotating with a Finite Acceleration
Journal of Fluid Science and Technology, 2008 A numerical study is made to delineate the time-dependent spin-up flow of a stratified fluid in a cylinder. The time-dependent process of a rotating and stratified fluid, in response to the alteration of the rotation rate of the container, is studied ...
