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, and these measurements can be obtained over an entire laser sheet. DGV has been used in wind tunnel applications at the Air Force Research Laboratory to make measurements of the flow associated with a vortex-tail interaction, which is typical of the flows seen on twin-tail fighter aircraft. This paper presents results obtained with the DGV instrument and discusses some unique challenges associated with incorporating this technique in large-scale wind tunnels.
