ACOUSTIC CAVITATION THEORY AND EQUIPMENT DESIGN PRINCIPLES FOR INDUSTRIAL APPLICATIONS OF HIGH-INTENSITY ULTRASOUND (Physics Research and Technology) [Paperback]

Alexey Peshkovsky, Sergei Peshkovsky, Paperback: 60 pages, Publisher: Nova Science Pub Inc (October 31, 2010), ISBN-10: 1617610933

Abstract

A multitude of useful physical and chemical processes promoted by ultrasonic cavitation have been described in laboratory studies. Industrial-scale implementation of the high-intensity ultrasound has, however, been hindered by several technological limitations, making it difficult to directly scale up the ultrasonic systems in order to transfer the results of the laboratory studies to the plant floor. High-capacity flow-through ultrasonic reactor systems required for commercial-scale processing of liquids can only be properly designed if the energy parameters of the cavitation region are correctly evaluated. Conditions which must be fulfilled to ensure an effective and continuous operation of an ultrasonic reactor system are provided in this book.

INDUSTRIAL-SCALE PROCESSING OF LIQUIDS BY HIGH-INTENSITY ACOUSTIC CAVITATION: THE UNDERLYING THEORY AND ULTRASONIC EQUIPMENT DESIGN PRINCIPLES [Hardcover]

Alexey Peshkovsky, Sergei Peshkovsky, Chapter 2 in "Sonochemistry Theory, Reactions, Syntheses and Applications", Publisher: Nova Science Pub Inc (October, 2010), ISBN-10: 1617286524

Abstract

A multitude of useful physical and chemical processes promoted by ultrasonic cavitation have been described in laboratory studies. Industrial-scale implementation of high-intensity ultrasound has, however, been hindered by several technological limitations, making it difficult to directly scale up ultrasonic systems in order to transfer the results of the laboratory studies to the plant floor. High-capacity flow-through ultrasonic reactor systems required for commercial-scale processing of liquids can only be properly designed if all energy parameters of the cavitation region are correctly evaluated. Conditions which must be fulfilled to ensure effective and continuous operation of an ultrasonic reactor system are provided in this chapter, followed by a detailed description of "shockwave model of acoustic cavitation", which shows how ultrasonic energy is absorbed in the cavitation region, owing to the formation of a spherical micro-shock wave inside each vapor-gas bubble, and makes it possible to explain some newly discovered properties of acoustic cavitation that occur at extremely high intensities of ultrasound. After the theoretical background is laid out, fundamental practical aspects of industrial-scale ultrasonic equipment design are provided.
