Excerpt from Notes on Magneto-Hydrodynamics, Vol. 4: Ohm's Law
Next, let us consider a two-fluid theory. The simplest such theory involves two mass-conservation equations, while retaining a single momentum and a single energy equation for the total fluid. We assume that a single equation of state involving energy, pressure, and both densities is given. Counting variables, compared to the one-fluid theory, we have an extra density (matched by an extra mass conservation equation) and also an extra velocity vector, e.g., the difference or diffusion velocity. In ordinary fluid dynamics, this extra velocity is taken care of by supplementing the system of conservation equations by a diffusion relation, e.g., an assertion that the difference velocity is proportional to the concentration gradient.

Paperback. Zustand: New. Print on Demand. This book presents a detailed analysis of the formal nature and domain of validity of Ohm's law and its application in magnetohydrodynamics. Ohm's law dictates the relationship between the electrical current density, electric field, and magnetic field in a conducting fluid and is often used to describe the behavior of plasmas. The author provides a comprehensive examination of the various forms of Ohm's law, including those that emerge under different physical conditions, and explores the interplay between friction and electromagnetic forces in determining the behavior of charged fluids. The analysis combines macroscopic and microscopic perspectives, drawing on both momentum conservation equations and particle trajectory analysis, to provide a thorough understanding of the underlying principles. The book is suitable for researchers and students in plasma physics, fluid dynamics, and electromagnetism, offering insights into the behavior of conducting fluids in the presence of magnetic fields.
