Droplet Sizing Research.

Abstract

A method to measure the size and velocity of individual particles in a flow is discussed. Results are presented for controlled monodisperse sprays and compared to flash photographs. Typical errors between predicted and measured sizes are less than 5%. Experimental results of the probe volume size are satisfactorily compared to a theoretical algorithm. A very simple optical apparatus is described and used to characterize a spray produced by a simplex nozzle. The size distribution and the Sauter mean diameter of this spray are presented as a function of position and pressure. Originator-supplied keywords: Droplet sizing, Particle velocity, Mass flux, Nonintrusive, Advanced laser diagnostics.
