Resumo

An experimental study of airblast atomization has been conducted using a specially designed atomizer in which the liquid is first spread into a thin sheet and then exposed on both sides to high-velocity air. The first results of this study, reported in reference [1], were confined to the effects of liquid properties, namely, viscosity, surface tension, and density on atomization quality. Since then the experimental data have been extended to include the influence of air properties, notably temperature and pressure, on-mean drop size. The purpose of this paper is to present these data and to show that the effects of both air and liquid properties on atomization quality are described by the following dimensionless equation: SMD/t=A(σeρe/t)0.5(Vaρa)−1.0(1+We/Wa)+B(ηe2/σeρat)0.425(1+We/Wa)2
