Power Ultrasonic Equipment - Practice and Application

(Link updated Oct 2013)

John Perkins has vast experience in power ultrasonics. Here he starts with the basics, covering the design and construction of piezo sandwich transducers and sonotrodes, before giving a detailed description of sonochemistry principles - cavitation, energy-density, monitoring power and amplitude.

The article concludes with a discussion of safety precautions and scaling-up the equipment to full production. It is aimed primarily at the chemist who wants to evaluate the use of sonochemistry techniques, but is also excellent reference material for anyone with an interest in power ultrasonics.
