Abstract

Experiments have been conducted to investigate the flowfield associated with two co-rotating vortices which represent the idealised vortex system associated with a novel rotor blade tip planform. These vortices were generated by two rectangular NACA 0015 half wings positioned upstream of the working section of a low speed windtunnel. Hot-wire measurements were conducted downstream of the generators using X-wire probes to document the strength, position and size of the vortices. A numerical model was utilised to provide an accurate means of determining vortex strength, position and size. Finally, the model was successfully extended to consider the rotation of the vortex system.
