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…
Heavy Particle Clustering in Inertial Subrange of High--Reynolds Number Turbulence
Keigo Matsuda, Katsunori Yoshimatsu, Kai Schneider
Direct numerical simulation of homogeneous isotropic turbulence shows pronounced clustering of inertial particles in the inertial subrange at high Reynolds number, in addition to t…
Machine learning-based vorticity evolution and superresolution of homogeneous isotropic turbulence using wavelet projection
Tomoki Asaka, Katsunori Yoshimatsu, Kai Schneider
A wavelet-based machine learning method is proposed for predicting the time evolution of homogeneous isotropic turbulence where vortex tubes are preserved. Three-dimensional convol…
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…
