Abstract
Flowfield measurements of the blade tip vortices from a rotating helic opter rotor model were performed by three component laser-Doppler velo cimetry (3D-LDV) and conventional (two component) particle image veloc imetry (PIV). In general, the results are in good correspondence, but also illustrate the different properties of both techniques: LDV offer s the capability of three-component measurements, whereas PIV captures the unsteadyness of the flowfield.
