This book serves as an introduction to magnetohydrodynamics (MHD) for graduate and advanced undergraduate engineering students. It may be used by engineers and physicists in research institutions and industry to become familiar with the particular phenomena of magnetothermohydraulics in technical liquid metal flows influenced by magnetic fields. The starting point of the book is the outcome of a recent nuclear fusion project. Therefore, it contains many new results that can be utilized for the design and optimization of various technical systems and processes.

The book deals with the theme of incompressible flows of electrically conducting fluids in hydraulic components. The main content of the book is a result of engineering research associated with the design of liquid metal cooling systems for fusion reactors. The book is well suited to serve as a guide for utilising magnetohydrodynamic means in other engineering disciplines such as in material processing, metallurgical engineering and power engineering.
