PAFEC VibroAcoustics - Ultrasonic Cleaning |
|
|
The example below illustrates the action of an ultrasonic cleaning device.
A cermic block is attached to a steel plate at the base of the tank
containing water. The ceramic is excited by a voltage applied across
the electrodes on the upper/lower surfaces. The vibration of the plate
radiates acoustic energy into the water. The surface at the top of the
tank is defined as free. Cavitation affects the properties of the acoustic
medium, and in particular the fluid becomes becomes lossy.
The example is a simple plain strain model.
