Abstract : The report describes an experimental feasibility investigation of the use of Raman scattering as a means of making point measurements of density in three-dimensional flows, such as, in turbocompressor machinery. A 3371 A ultraviolet pulsed nitrogen laser was used as the laser source. The major problem area considered was the ability to make measurements close to the walls and in confined internal geometries. The density in a flow past a heated cylinder was measured by both the Raman technique and a standard interferometer and the two method were shown to agree. (Author)
