Laser Interferometer for Droplet-Sizing Application

Abstract

A particle-sizing laser interferometer was developed for single particle, in situ sizing and velocity measurement of water droplets in a wind tunnel used for icing studies. Droplet diameters were in the range from 5 to 80 micrometers, flow velocity was in excess of 100 meters per second, and droplet number densities were a few hundred per cubic centimeter. Both off-axis and on- axis light collection designs were evaluated and are described. Variation of the sample volume with particle size is discussed.
