Abstract
Planar Doppler Velocimetry (PDV) is a laser-based diagnostic which measures velocity based on tin-Doppler shift of single frequency laser light scattered off seed particles in the flow field. This technique enables the acquisition of instantaneous velocity measurements over an entire laser sheet. This paper presents results obtained with the PDV instrument in a large-scale wind tunnel test. Characterization and analysis of system accuracy is addressed and an application of the PDV technique for characterization of a leading edge vortex system is presented.
