Compound atomization by air action. The effect of liquid properties.

Abstract

The study of the effect of liquid physical properties on atomization is an important subject. In this study, the ethyl alcohol-water solution and the glycerin-water solution are used for changing the properties. The correlation between density, viscosity and surface tension of a liquid is obtained. The relationship between SMD and the liquid physical properties is clarified. How the liquid physical properties affect the atomization is examined in detail with a D7-2-2-type nozzle which was used in the former report. An experimental equation including the liqued physical properties is obtained for SMD near the singular point.
