Numerical Analysis of Ultrasonic Nebulizer for Onset Amplitude of Vibration with Atomization Experimental Results

In this study, the onset amplitude of initial capillary surface wave for ultrasonic atomization fluids has been implemented. The design and characterization 485 kHz microfabricated silicon-based nozzles are presented concept economic energy development. Each nozzle is composed a silicon resonator piezoelectric drive section consisting three Fourier horns. required minimum to atomize liquid droplets verified by COMSOL Multiphysics simulation software clarify experimental data. study reports vibrational (onset) 0.365 μm at device bottom under designated frequency kHz. agrees well with suggested concerning corresponding velocity in simulation. While operating, deionized water was initially atomized into microdroplets given electrode voltage 5.96 V. Microdroplets steadily continuously formed after feeding rate optimized. This newly designed atomizer facilitates development resonance frequency. A finite electric driving promote not only modern green industry, but also exploration noninvasive, microencapsulated drug delivery local spray needs.
