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 ...

The tertiary current distributions on rotating electrodes are studied in this work. An acid copper sulfate electrolyte is used within an electrochemical cell of practical dimensions. The distributions of ion concentrations are obtained by the two-dimensional fluid flow simulation and the solution of mass-transport equations based on axial symmetry.

In the Fluid Jet Method, a polishing fluid is compressed and delivered through a nozzle, allowing the spot area to become continuously replenished with abrasives and coolant. Process parameters include: Abrasive type and concentration, Inlet pressure, Nozzle diameter, Impingement angle, Surface feed of spot. The simulation uses COMSOL’s turbulent 2-phase flow model, with the incompressible ...

In recent years, optical manipulation using optical radiation pressure has been widely studied. In this study, the radiation pressure exerted on various kinds of microscopic objects with different laser beams was evaluated by COMSOL Multiphysics software. By changing beam shapes, microscopic objects can be trapped and rotated. This paper is in Japanese.
