Absolute instability of the von Kármán, Bödewadt and Ekman flows between a rotating disc and a stationary lid.
The stability of a family of boundary-layer flows, which includes the von Kármán, Bödewadt and Ekman flows for a rotating incompressible fluid between a rotating disc and a stationary lid, is investigated. Numerical computations with the use of a spectral method are carried out to analyse absolute and convective instability. It is shown that the stability of the system is enhanced with a decrease in distance between the disc and the lid.
