Abstract

The size distribution of drops formed from four different diameter nozzles (d=l.O, 1.6, 2.6 and 3.5 mm) was measured over the flow rate range of 0.17 to 3.0 cm3/s (below jetting). Kerosene was used as the dispersed phase and distilled water was used as the continuous phase. The experimental drop size distributions were described adequately by the upper limit number and volume distributions. Plots of the maximum and the minimum diameters versus the mean diameter yielded straight line with slopes of 1.11 and 0.87, respectively.

Abstract

La distribution de taille des gouttes formées par quatres buses de pulverisation du diamére différent (d=1.O, 1.6, 2.6 et 3.5 mm) était mesurée pour vitesses volumetriques d'écoulement de 0.17 à 3.0 cm3/s. Cerosène était utilisé comme phase dispersée et cau distillée cornme phase continue. Les distributions experimentelles de taille des gouttes étaient suffisament décrites par le nombre de la haute limite et par les distributions volumetriques. Les diagrammes du diamétre maxima1 et minimal en fonction de diamétre moyen sont des lignes droites avec des inclinaisons de 1.11 et 0.87 respectivement.
