| description | Three dimensional steady and unsteady velocity distributions in the axial flow fan were
measured using a hot wire probe for various operational conditions, various rotational
speeds and various measuring positions. For measuring the velocity distributions in the blade
passage, a specially designed and manufactured hot wire traversing apparatus was used.
Steady velocity distributions, turning angles, effects of incident to the cascade, flow leakage
through the tip clearance and effects of the flow separation show the flow phenomena
through the blade passages. Unsteady velocity distributions show time dependent procedures
of the wake flowing through the moving blade passage. Considering these results of
measurements, the effects of the upstream stationary blade and the effects of Reynolds
number on the flow were considered. |
