Resistive Drift Waves in a Bumpy Torus

Abstract

A computational study of resistive drift waves in the edge plasma of a bumpy torus is presented. The magnetohydrodynamic equilibrium is obtained from a three-dimensional local equilibrium model. The use of a local magnetohydrodynamic equilibrium model allows for a computationally-efficient systematic study of the impact of the magnetic field structure on drift wave stability.

Modeling Solution of Nonlinear Dispersive Partial Differential Equations Using the Marker Method

“…The markers are advanced in time according to the characteristics ('equations of motion') of the underlying partial differential equation (PDE) associated with the problem. Marker methods are particularly useful for collisionless problems [1][2][3][4]. However, in many applications of interest (e.g.…”
