Abstract:

The use of holography in studying certain fluid mechanics problems was investigated. This effort specifically examined the application of holography to 1 high speed supersonic flow fields by injecting different liquid jets perpendicularly into a Mach 3 gas stream to observe how jet breakup occurs, and 2 the atomization characteristics droplet size and spatial distribution of a liquid jet injected into quiescent, atmospheric air. The holograms were recorded in the off-axis, Fresnel, transmission arrangement. The analytical method for processing three-dimensional droplet data consisted of a system of computer programs which operated on the droplet size and spatial coordinates to determine size, mass, number and spatial distribution. Two methods for retrieving holographic data were devised.
