Simultaneous measurements of velocities and sizes of particles in flows using a combined system incorporating a top-hat beam technique
Abstract
A combined system using laser Doppler velocimetry for velocity measurements and a top-hat laser beam technique for simultaneous sizing is described. Measurements have been carried out on various sprays produced by a TSI-3050 generator. Results are compared with scattering theory, free-fall velocity computations, and holography measurements. The conclusion is that the measurements obtained from the combined system are satisfactory.
