Some comments on the characterization of drop-size distribution in sprays
Abstract
An attempt is made to explain and clarify some of the anomalies and misconceptions that are encountered in the literature on drop-size distributions in sprays. The key features and relative merits of the various parameters that have been put forward to describe drop-size distribution, such as the Rosin-Rammler equation, Droplet Uniformity Index, Relative Span Factor, Dispersion Index, and MMD/SMD ratio, are discussed. It is shown that although any suitable diameter may be used as the representative diameter in the Rosin-Rammler distribution function, the Sauter mean diameter (SMD) provides the best indication of the atomization quality of a spray.
