Abstract

In unstable airflows, it is found that often the seed particles used to make laser Doppler anemometry measurements of fluid velocities follow complicated trajectories in even very small fringe volumes. A technique to obtain maximum particle-trajectory information from the scattered light signal is described. The use of this technique to measure fluid-motion characteristics in regions of unstable flow down to 10-μm scale inhomogeneities is described.
