Conservative discretization of the Landau collision integral
Eero Hirvijoki, Mark Adams
We describe a density-, momentum-, and energy-conserving discretization of the nonlinear Landau collision integral. The method is suitable for both the finite-element and discontin…
Nonlinear Resistivity for Magnetohydrodynamical Models
Manasvi Lingam, Eero Hirvijoki, David Pfefferlé +2
A new formulation of the plasma resistivity that arises from the collisional momentum-transfer rate between electrons and ions is presented. The resistivity computed herein is show…
An advection-diffusion model for cross-field runaway electron transport in perturbed magnetic fields
Konsta Särkimäki, Eero Hirvijoki, Joan Decker +2
Disruption-generated runaway electrons (RE) present an outstanding issue for ITER. The predictive computational studies of RE generation rely on orbit-averaged computations and, as…
Fluid moments of the Landau collision operator
Eero Hirvijoki, Manasvi Lingam, David Pfefferlé +3
One important problem in plasma physics is the lack of an accurate and complete description of Coulomb collisions in associated fluid models. To shed light on the problem, this Let…
