Ion Acoustic Travelling Waves
G. M. Webb, R. H. Burrows, X. Ao +1
Models for travelling waves in multi-fluid plasmas give essential insight into fully nonlinear wave structures in plasmas, not readily available from either numerical simulations o…
Multi-Symplectic Magnetohydrodynamics
G. M. Webb, J. F. McKenzie, G. P. Zank
A multi-symplectic formulation of ideal magnetohydrodynamics (MHD) is developed based on a Clebsch variable variational principle in which the Lagrangian consists of the kinetic mi…
Local and Nonlocal Advected Invariants and Helicities in Magnetohydrodynamics and Gas Dynamics I: Lie Dragging Approach
Gary M. Webb, Brahmananda Dasgupta, James F McKenzie +2
In this paper we discuss conservation laws in ideal magnetohydrodynamics (MHD) and gas dynamics associated with advected invariants. The invariants in some cases, can be related to…
Local and Nonlocal Advected Invariants and Helicities in Magnetohydrodynamics and Gas Dynamics II: Noether's Theorems and Casimirs
G. M. Webb, B. Dasgupta, J. F. McKenzie +2
Conservation laws in ideal gas dynamics and magnetohydrodynamics (MHD) associated with fluid relabelling symmetries are derived using Noether's first and second theorems. Lie dragg…
