Acoustics of Nanodispersed Magnetic Fluids presents key information on the acoustic properties of magnetic fluids. The book is based on research carried out by the author as well as on many publications in both the Russian and foreign scientific literature from 1969 onwards.
It describes a wide variety of topics, which together lay the foundation of a new scientific research area: the acoustics of nanodispersed media. The book examines the nanoscale structure of matter in specific areas and discusses the following:
- Model theory and known features of the propagation of sound waves in magnetised fluids
- Acoustomagnetic and magnetoacoustic effects in magnetic fluids
- Acoustomagnetic spectroscopy of vibrational modes in the liquid-shell system
- Vibration and rheological effects of magnetised magnetic fluids
- Acoustometry of the shape of magnetic nanoaggregates and non-magnetic microaggregates
- Acoustogranulometry, a new method for studying the physical properties of magnetic nanoparticles dispersed in a carrier fluid
The book is a valuable resource for engineers and researchers in the fields of acoustics, physical acoustics, magnetic hydrodynamics, and rheology physics. The experimental methods, which are described in this book, are based on incompatible features of magnetic fluids, i.e. strong magnetism, fluidity and compressibility. As a result, this can find industrial application in advanced technology. It is also useful for both advanced undergraduate and graduate students studying nanotechnology, materials science, physical and applied acoustics.
