The boundary layer on a disk at rest in a rotating fluid
Abstract
The boundarylayer equations for the flow along an immobile disk of finite radius placed in a (solidbody) rotating fluid are solved. Due to reversed flow in the boundary layer this leads to a socalled singular parabolic equation with boundary values available along the complete boundary. This boundaryvalue problem is solved by line iteration and underrelaxation in the same way as for an elliptic problem. The torque exerted on the disk is calculated.
