Simulation of edge localized mode heat pulse using drift-kinetic ions and Boltzmann electrons
Autor: Mikhail Dorf, Ilon Joseph, M. R. Dorr
Publikováno v: Nuclear Materials and Energy, Vol 19, Iss, Pp 330-334 (2019)
This article reports on 1D+2V heat pulse propagation studies using the COGENT guiding center kinetic code. The model uses magnetized kinetic ions and a simple Boltzmann electron model. Results agree with previous kinetic and fluid modeling benchmark

Continuum gyrokinetic simulations of edge plasmas in single-null geometries
Autor: Mikhail Dorf, M. R. Dorr
Publikováno v: Physics of Plasmas. 28:032508
The first continuum gyrokinetic calculations of electrostatic ion scale turbulence are presented for the case of a diverted tokamak geometry. The simulation model solves the long-wavelength limit of the full-F gyrokinetic equation for ion species cou

Progress with the COGENT Edge Kinetic Code: Implementing the Fokker-Planck Collision Operator
Autor: Ronald H. Cohen, Mikhail Dorf, Jeffrey Hittinger, T.D. Rognlien, M. R. Dorr
Publikováno v: Contributions to Plasma Physics. 54:517-523
Here, COGENT is a continuum gyrokinetic code for edge plasma simulations being developed by the Edge Simulation Laboratory collaboration. The code is distinguished by application of a fourth-order finite-volume (conservative) discretization, and mapp

Reduced Electron Models for Edge Simulation
Autor: M. R. Dorr, Ronald H. Cohen, Mikhail Dorf
Publikováno v: Contributions to Plasma Physics. 52:529-533
We consider the treatment of electrons in kinetic simulations of edge plasmas. A fully kinetic treatment of electrons is expensive because of the short timescales associated with rapid streaming along field lines. Hence we survey a number of reduced

High-order, finite-volume methods in mapped coordinates
Autor: Phillip Colella, Jeffrey Hittinger, Daniel F. Martin, M. R. Dorr
Publikováno v: Journal of Computational Physics. 230:2952-2976
We present an approach for constructing finite-volume methods for flux-divergence forms to any order of accuracy defined as the image of a smooth mapping from a rectangular discretization of an abstract coordinate space. Our approach is based on two
