Modeling of the initial droplet size distribution function in the spray formed by impinging jets

Abstract

The modeling of thin sheets formed by impinging jets and the ideas employed by dombrowski for disintegration of viscous liquid sheets can be merged to allow the sizing and distribution of the droplets formed by colliding jets." This paper presents a method for the calculation of the mitial droplet size distribution function and its moments (i.e., the Sauter mean diameter, the length mean diameter, the surface mean diameter, the surface-diameter mean, the volume mean diameter, the volume-diameter mean, and the geo-metric mean diameter), for, as it is well known, each one of them hás its own preferred field of application. In particular the Sauter mean diameter, a parameter of wide application in the field of cumbustion, is shown to possess a minimum at a certain value of the impinging angle for several liquids.
