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…
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…
Transport, flow topology and Lagrangian conditional statistics in edge plasma turbulence
Benjamin Kadoch, Diego del-Castillo-Negrete, Wouter J. T. Bos +1
Lagrangian statistics and particle transport in edge plasma turbulence are investigated using the Hasegawa-Wakatani model and its modified version. The latter shows the emergence o…
Estimation of the thermal properties of an historic building wall by combining Modal Identification Method and Optimal Experiment Design
Julien Berger, Benjamin Kadoch
The estimation of wall thermal properties by \emph{in situ} measurement enables to increase the reliability of the model predictions for building energy efficiency. Nevertheless, r…
Clustering of Inertial Particles in Turbulent Flow Through a Porous Unit Cell
Sourabh V. Apte, Thibault Oujia, Keigo Matsuda +3
Direct numerical simulation is used to investigate effects of turbulent flow in the confined geometry of a face-centered cubic porous unit cell on the transport, clustering, and de…
Angular multiscale statistics of Lagrangian trajectories in turbulence
Wouter Bos, Benjamin Kadoch, Kai Schneider
The angle between subsequent particle displacement increments is evaluated as a function of the timelag in isotropic turbulence. It is shown that the evolution of this angle contai…
Conditional vorticity budget of coherent and incoherent flow contributions in fully developed homogeneous isotropic turbulence
Michael Wilczek, Benjamin Kadoch, Kai Schneider +2
We investigate the conditional vorticity budget of fully developed three-dimensional homogeneous isotropic turbulence with respect to coherent and incoherent flow contributions. Th…
Origin of Lagrangian Intermittency in Drift-Wave Turbulence
Benjamin Kadoch, Wouter Bos, Kai Schneider
The Lagrangian velocity statistics of dissipative drift-wave turbulence are investigated. For large values of the adiabaticity (or small collisionality), the probability density fu…

B. Kadoch, D. del-Castillo-Negrete, W. J. T. Bos +1
A study of the relationship between Lagrangian statistics and flow topology in fluid turbulence is presented. The topology is characterized using the Weiss criterion that provides…
Inertial range scaling of the scalar flux spectrum in two-dimensional turbulence
Wouter Bos, Benjamin Kadoch, Kai Schneider +1
Two-dimensional statistically stationary isotropic turbulence with an imposed uniform scalar gradient is investigated. Dimensional arguments are presented to predict the inertial r…
Extreme Lagrangian acceleration in confined turbulent flow
Benjamin Kadoch, Wouter Bos, Kai Schneider
A Lagrangian study of two-dimensional turbulence for two different geometries, a periodic and a confined circular geometry, is presented to investigate the influence of solid bound…
