Abstract

Doppler Global Velocimetry (DGV) is a new laser-based diagnostic which complements existing measurement capabilities for wind tunnel applications. Measurements of velocity are based on determining the Doppler shift of single frequency laser light scattered off particles in the flow field. This technique is capable of making simultaneous measurements over an entire laser sheet. This paper presents results obtained with the DGV instrument in both calibration and wind tunnel test setups. Characterization and analysis of isystem accuracy is addressed with the calibration setups. Example applications of the DGV technique for measurements on a wind tunnel model are also presented.
