AEROSOLS PRODUCED BY SPINNING DISCS - A REAPPRAISAL

Aerosol droplets in monodisperse sprays produced by spinning disc gene rators are shown to correlate with a simple law when the controlling p arameters are represented in an appropriate dimensionless form. This c orrelation holds for liquid of widely differing physical properties, v iz. with surface tensions varying between 31.5 and 465 dyne/cm. The re sults implies that the Bond number based on the droplet size (i.e., th e ratio of the body force to the surface tension) has a constant value of approximately 1.63.
