Ultrasonic Atomization: New Spray Characterization Approaches

چکیده
In particle engineering, spray drying is an essential technique that depends on producing sprays, ideally made of equal-sized droplets. Ultrasonic sprays appear to be the best option achieve it, and Faraday waves are background mechanism ultrasonic atomization. The characterization in this atomization strategy commonly related relation between characteristic drop sizes capillary length produced by forcing frequency wavy patterns thin liquid films. However, although approach practical when intended outcome produce with droplets same size, diverse real applications. Therefore, adequate size paramount establishing relations empirical approaches proposed literature actual operating conditions. sense, work explores new applied different solvents. first two introduced role redundancy measurements avoid resolution limitation measurement compare using regular versus variable bin widths building histograms size. Another tool Drop Size Diversity understand limitations characterizing solely based representative diameters or moments distributions. results obtained emphasize: lack universality a diameter associated waves; variability induced both properties flow rate outcome, namely, lower lengths smaller but less efficiently; higher sensibility polydispersion heterogeneity degrees build size; diversity for rates expressed presence multiple clusters similar characteristics leading multimodal distributions; gamma log-normal mathematical probability functions ones describe organization data sprays.

متن کاملUltrasonic atomization of liquids in drop-chain acoustic fountains.
When focused ultrasound waves of moderate intensity in liquid encounter an air interface, a chain of drops emerges from the liquid surface to form what is known as a drop-chain fountain. Atomization, or the emission of micro-droplets, occurs when the acoustic intensity exceeds a liquid-dependent threshold. While the cavitation-wave hypothesis, which states that atomization arises from a combina...
