Ultrasonic Techniques for Fluids Characterization

by Malcolm J.W. Povey

Overview

This book is a comprehensive and practical guide to the use of ultrasonic techniques for the characterization of fluids. Focusing on ultrasonic velocimetry, the author covers the basic topics and techniques necessaryfor successful ultrasound measurements on emulsions, dispersions, multiphase media, and viscoelastic/viscoplastic materials. Advanced techniques such as scattering, particle sizing, and automation are also presented. As a handbook for industrial and scientific use, Ultrasonic Techniques for Fluids Characterization is an indispensable guide to chemists and chemical engineers using ultrasound for research or process monitoring in the chemical, food processing, pharmaceutical, cosmetic, biotechnology,and fuels industries.

Editorial Reviews

For chemists and chemical engineers engaged in research or in monitoring processes in such industries as chemicals, food, and pharmaceuticals. Focusing on ultrasonic velocimetry, Povey (food science, U. of Leeds, England) explains how to measure a number of features in emulsions, dispersions, multiphase media, and viscoelastic and viscoplastic materials. He also presents such advanced techniques as scattering, particle sizing, and automation. Suitable for novices or veterans of sonography and as a text for a senior or first-year graduate course.
