Size and Velocity Characterization of Asymmetric Twin-Fluid Nebulizer Sprays." Proceedings of the ASME 2006 International Mechanical Engineering Congress and Exposition

C. Lopez, and P.E. Sojka

An investigation and comparison of how sprays are formed in two different asymmetric twin fluid (parallel-path) nebulizer sprays. Information on the droplet size, velocity, and dispersion are obtained for an LB-30 and MiraMist nebulizer are determined. The information is used to show the evolution of the spray profile from the tip and by the time the spray reaches a distance of approximately 8 orifice diameters a highly symmetric mist is observed. The experimental data lead to a number of conclusions which were expected namely: drop sizes are directly proportional to liquid mass flow, liquid flow rate had little if any effect on droplet velocities, drop size and drop velocity demonstrate an inverse relationship, and that drop sizes are effectively constant while the axial velocity decreases with distance from the nebulizer tip.
