Simulations of scrape-off layer power width for EAST H-mode plasma and ITER 15 MA baseline scenario by 2D electrostatic turbulence code
X. Liu, A. H. Nielsen, J. J. Rasmussen +4
The scrape-off layer power width (λ_q) is an important parameter for characterizing the divertor heat loads. Many experimental, theoretical, and numerical studies have been perform…
A self-consistent model of the plasma staircase and nonlinear Schrödinger equation with subquadratic power nonlinearity
Alexander V. Milovanov, Jens Juul Rasmussen, Guilhem Dif-Pradalier
A new basis has been found for the theory of self-organization of transport avalanches and jet zonal flows in L-mode tokamak plasma, the so-called "plasma staircase." The jet zonal…
Lévy flights on a comb and the plasma staircase
Alexander V. Milovanov, Jens Juul Rasmussen
We formulate the problem of confined Lévy flight on a comb. The comb represents a sawtooth-like potential field , with the asymmetric teeth favoring net transport in a prefer…
ExB mean flows in finite ion temperature plasmas
J. Madsen, J. Juul Rasmussen, V. Naulin +1
The impact of ion pressure dynamics on E x B mean flows is investigated. Using a simplified, two-dimensional, drift ordered fluid model in the thin-layer approximation, three stres…
Collisional transport across the magnetic field in drift-fluid models
Jens Madsen, Volker Naulin, Anders Henry Nielsen +1
Drift ordered fluid models are widely applied in studies of low-frequency turbulence in the edge and scrape-off layer regions of magnetically confined plasmas. Here, we show how co…
Simulation of transition dynamics to high confinement in fusion plasmas
A H. Nielsen, G. S. Xu, J. Madsen +3
The transition dynamics from the low (L) to the high (H) confinement mode in magnetically confined plasmas is investigated using a first-principles four-field fluid model. Numerica…
