Plasma-neutral collision operators for hydrogen isotopes: kinetic and gyrokinetic descriptions, comparison to fluid
Matthieu Protais, Guilhem Dif-Pradalier, Yanick Sarazin +4
Plasma-neutral interactions critically affect the edge dynamics of magnetically confined fusion devices. Neutral atoms modify ion and electron velocity distributions, potentially a…
The 21N-moment multi-temperature coefficients for Zhdanov closure
Madhusudan Raghunathan, Yannick Marandet, Hugo Bufferand +4
We provide the 21N-moment multi-temperature collision coefficients for the Boltzmann collision operator using the Sonine-Hermite polynomial ansatz in the style of Zhdanov et al. Fi…
Multi-temperature Generalized Zhdanov Closure for Scrape-Off Layer/Edge Applications
Madhusudan Raghunathan, Yannick Marandet, Hugo Bufferand +4
The derivation of the multi-temperature generalized Zhdanov closure is provided starting from the most general form of the left hand side of the moment averaged kinetic equation wi…
Generalized Collisional Fluid Theory for Multi-Component, Multi-Temperature Plasma Using The Linearized Boltzmann Collision Operator for Scrape-Off Layer/Edge Applications
Madhusudan Raghunathan, Yannick Marandet, Hugo Bufferand +4
Grad's method is used on the linearized Boltzmann collision operator to derive the most general expressions for the collision coefficients for a multi-component, multi-temperature…
Fluid and kinetic modelling for non-local heat transport in magnetic fusion devices
Guido Ciraolo, Hugo Bufferand, Pierfrancesco Di Cintio +7
In order to improve the presently used ad hoc flux limiter treatment of parallel heat flux transport in edge plasma fluid codes we consider here a generalized version of the Fourie…
Kinetic equations for Stark line shapes
J. Rosato, H. Capes, Y. Marandet +2
The BBGKY formalism is revisited in the framework of plasma spectroscopy. We address the issue of Stark line shape modeling by using kinetic transport equations. In the most simpli…
Linear transport in stochastic media. Application to neutral transport in turbulent plasmas
Y. Marandet, A. Mekkaoui, D. Reiter +8
This work addresses linear transport in turbulent media, with emphasis on neutral particle (atoms, molecules) transport in magnetized fusion plasmas. A stochastic model for turbule…
Spectral line shape modeling and ion temperature fluctuations in tokamak edge plasmas
Y. Marandet, J. W. Dufty
In this work, we use a passive advection model for ion temperature fluctuations, in order to investigate their effects on Doppler Spectral line shapes. The relevance of the model i…
Spectral line shapes in low frequency turbulent tokamak plasmas
Y. Marandet, H. Capes, L. Godbert-Mouret +2
In this paper we investigate the influence of low frequency turbulence on Doppler spectral line shapes in magnetized plasmas. Low frequency refers here to fluctuations whose typica…
