Abstract
A new non-intrusive flow diagnostics instrumentation system, Doppler g lobal velocimetry, is presented. The system is capable of making simul taneous three-component velocity measurements within a selected measur ement plane at video camera rates. These velocity images can provide t he researcher with spatial and temporal information about the flow fie ld in a global sense. The investigation of a vortical flow above a 75- degrees delta wing comparing standard three-component fringe-type lase r velocimetry measurements with Doppler global velocimetry measurement s is presented.
