High Resolution Velocity Measurements Upstream and Downstream of an Axial Flow Fan Rotor (original) (raw)

An important topic of research at The Budapest University of Technology and Economics, Department of Fluid Mechanics is that of axial flow fans of controlled vortex design. In this ongoing research, a computational fluid dynamics simulation has been developed for the further investigation of the flow phenomena developing in the vicinity of the rotor. In order to fully validate this simulation, detailed velocity measurements have been carried out on the flow both upstream and downstream of a rotor designed using a controlled vortex design method incorporating circumferential forward skew. These measurements have already been used in order to validate the pitchwise averaged data of the computational fluid dynamics simulation, with this article focusing on the validation of the pitchwise resolved data.
