This book explores the physics and technology of magnetohydrodynamic conversion of chemical energy from explosives and propellants into powerful bursts of electrical energy. It examines three types of converters: the explosive MHD generator, the explosively-driven magnetic generator, and the pulsed MHD generator with a quasi-stationary flow of combustion products from propellants. The text delves into the physical challenges that determine the efficiency of energy conversion and identifies the optimal areas for utilizing these generators. Featuring results from original research and developments conducted by the authors over the past 20 years, this book is an essential resource for researchers, engineers, graduate students, and specialists in the fields of electro- and plasma physics, as well as direct energy conversion methods.
