Abstract
The problem of axisymmetric laminar flow of a viscous incompressible fluid that occurs between a stationary and a rotating disk subjected to a uniform radial throughflow has been numerically investigated for a large range of flow parameters. Results show that the basic flow structure is rather complex and depends strongly on both the rotational and the throughflow Reynolds numbers. In general, the basic unicellular structure has been observed. With the increase of the throughflow Reynolds number, a multicellular flow structure may be found. The phenomenon of multiple solutions has been clearly observed for cases with sufficiently high rotational Re and / or high throughflow Re. Among these solutions, stable as well as unstable solutions have been determined by applying Rayleigh 's stability criterion. The influence of the starting conditions on the stability of the flow has also been investigated for various ranges of flow parameters.
