Opis

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.

• Appeals to anyone using ultrasound to study fluids
• Provides the first detailed description of the ultrasound profiling technique for dispersions
• Describes new techniques for measuring phase transitions and nucleation, such as water/ice and oil/fat
• Presents the latest ultrasound techniques for particle sizing in concentrated systems
• Explains new techniques for compressibility measurements in dispersions and fluids, including cell suspensions
• Contains a detailed treatment of ultrasound scattering theory
• Written by one of the leading researchers in the field
• Includes over 350 references to the primary literature
