THE BOUNDARY LAYER ON A DISK AT REST IN A ROTATING FLUID
( Department of Mathematics, University of Groninge PO Box 800, 9700 AV Groningen, The Netherlands )
The boundary-layer equations for the flow along an immobile disk of finite radius placed in a (solid body) rotating fluid have been solved. Due to reversed flow in the boundary layer this leads to a so-called singular parabolic equation with boundary values available along the complete boundary. This boundary-value problem has been solved by line iteration and underrelaxation in the same way as for an elliptic problem. The torque exerted on the disk has been calculated.
