Abstract
Fluid forces acting on a rotating centrifugal impeller in whirling motion are studied experimentally. In the first report, a two-dimensional impeller installed in a parallel-walled vaneless diffuser was used. Here in the second report, fluid forces on a three-dimensional impeller in a vaned diffuser are investigated when it is forced to whirl on a circular orbit with a constant eccentricity. The experimental apparatus is improved to be able to synchronize the whirling phase with the rotating one. Although a strong interaction between rotor vanes and guide vanes is observed at a certain specific whirling ratio, the fluid forces averaged throughout one whirling period, which are dominant for the stability of the rotating system, exert a damping effect on the rotor under most operating conditions.
