Shafranov. Magnetohydrodynamics (MHD) plays a crucial role in astrophysics, planetary magnetism, engineering and controlled nuclear fusion. This comprehensive textbook emphasizes physical ideas, rather than mathematical detail, making it accessible to a broad by: The mathematical problem for the stability of magnetostatic equilibria is made tractable due to the formulation of the so-called energy principle.

It turns out that when MHD equilibria contain flows that are spatially dependent, the power of the energy principle is weakened significantly, and there has been a general tendency to rely on the. The domain for our resistive MHD benchmark is a straight cylinder with periodic ends. For a selected helical perturbation (∼e imθ+i2πnz/L z, where m and n are fixed integers, and L z is the cylinder length), there exists a concentric cylindrical surface within the domain where the perturbation has constant phase along the equilibrium magnetic field lines, which lie within the Cited by: Linear and nonlinear stability analysis for two-dimensional ideal.
