Characteristic Mapping Method for Vlasov-Poisson with BGK-collisions
Xi-Yuan Yin, Philipp Krah, Zetao Lin +2
This work presents the first steps for simulating kinetic plasmas with collisions using the characteristic mapping method (CMM). The CMM is a semi-Lagrangian method that explores a…
Anisotropy and intermittency in drift-wave turbulence with zonal flows: a two-dimensional continuous wavelet analysis
Katsunori Yoshimatsu, Zetao Lin, Hideaki Miura +1
We examine anisotropy and spatial intermittency at small scales in drift-wave turbulence with zonal flows. We use a two-dimensional directional continuous wavelet transform, which…
A Hybrid semi-Lagrangian Flow Mapping Approach for Vlasov Systems: Combining Iterative and Compositional Flow Maps
Philipp Krah, Zetao Lin, R. -Paul Wilhelm +4
We propose a hybrid semi-Lagrangian scheme for the Vlasov--Poisson equation that combines the Numerical Flow Iteration (NuFI) method with the Characteristic Mapping Method (CMM). B…
Nondiffusive transport of inertial heavy impurities in drift-wave turbulence
Zetao Lin, Benjamin Kadoch, Sadruddin Benkadda +1
We investigate the transport behavior of tungsten impurities with finite inertia in drift-wave turbulence using the Hasegawa-Wakatani model. Unlike previous tracer-based models, ou…
Multiscale geometrical Lagrangian statistics of heavy impurities in drift-wave turbulence
Zetao Lin, Benjamin Kadoch, Saddrudin Benkadda +1
We investigate the behavior of heavy impurities in edge plasma turbulence by analyzing their trajectories using the Hasegawa-Wakatani model. Through direct numerical simulations, w…
Tessellation-based analysis of impurity clustering in the edge plasma of tokamaks
Zetao Lin, Thibault Maurel--Oujia, Benjamin Kadoch +2
Confinement quality in fusion plasma is significantly influenced by the presence of heavy impurities, which can lead to radiative heat loss and reduced confinement. This study expl…
Synthesizing impurity clustering in the edge plasma of tokamaks using neural networks
Zetao Lin, Thibault Maurel-Oujia, Benjamin Kadoch +4
This work investigates the behavior of impurities in edge plasma of tokamaks using high-resolution numerical simulations based on Hasegawa--Wakatani equations. Specifically, it foc…
