Design of Traveling Wave Ultrasonic Vibration Disk for Nano-particles in Liquid DispersionJ. Muraoka, and T. Suzuki
Yamagata Research Institute of Technology
The traveling wave ultrasonic vibration disks for dispersion of particles were designed by using of FEM analysis. The vibration disks are required specific vibration pattern, which contains three nodal lines. The vibration disk thickness was calculated to be matched the resonance frequency of bolted langevin type transducer and the specific vibration pattern. The alignment of the transducer was calculated to minimize the driving force?In addition, acoustics field and flow field caused by the vibration disk was simulated.
