Inertial magnetohydrodynamics
M. Lingam, P. J. Morrison, E. Tassi
A version of extended magnetohydrodynamics (MHD) that incorporates electron inertia is obtained by constructing an action principle. Unlike MHD which freezes in magnetic flux, the…
The action principle for generalized fluid motion including gyroviscosity
M. Lingam, P. J. Morrison
A general set of fluid equations that allow for energy-conserving momentum transport by gyroscopic motion of fluid elements is obtained. The equations are produced by a class of ac…
Action Principles for Extended MHD Models
I. Keramidas Charidakos, M. Lingam, P. J. Morrison +2
The general, non-dissipative, two-fluid model in plasma physics is Hamiltonian, but this property is sometimes lost or obscured in the process of deriving simplified (or reduced) t…
Hamiltonian and action formalisms for two-dimensional gyroviscous MHD
P. J. Morrison, M. Lingam, R. Acevedo
A general procedure for constructing action principles for continuum models via a generalization of Hamilton's principle of mechanics is described. Through the procedure, an action…
