Drop-Size Measurement of Two-Fluid Atomizer

Rotary Atomizer Drop Size Distribution Database

Wind tunnel measurements of drop size distributions from Micronair AU4000 and AU5000 rotary atomizers were collected to develop a database for model use. The measurements varied tank mix, flow rate, air speed, and blade angle conditions, which were correlated by multiple regressions (average R2 = 0.995 for AU4000 and 0.988 for AU5000). This database replaces an outdated set of rotary atomizer d...

Two Fluid Drop Snap-Off Problem: Experiments and Theory

We address the dynamics of a drop with viscosity lh breaking up inside another fluid of viscosity h. We track the time evolution of the drop near snap-off in the experiments and then compare with a scaling theory developed for l 1. The theory is in excellent agreement with both the experiments and the previous simulations of Lister and Stone. Finally, we also investigate the l dependence of the...

A pharmacokinetic study of midazolam in dogs: nasal drop vs. atomizer administration.

PURPOSE The purpose of this investigation was to compare the pharmacokinetics of midazolam following intravenous, intranasal drop, and nasal-atomizer administration in beagle dogs. METHODS Six animals weighing 9-13 kg were used in a repeated-measure design, group assignment based on route of drug administration. Midazolam (1.5 mg/kg) was administered with the delivery route based on group ass...
