Multiresolution analysis on tessellation graphs for inertial particle dynamics
Keigo Matsuda, Thibault Maurel-Oujia, Kai Schneider
A multiresolution technique on tessellation graphs for particle dynamics is proposed. This allows to split spatial field data given on millions of discrete particle positions into…

Singularity formation of vortex sheets in 2D Euler equations using the characteristic mapping method
Julius Bergmann, Thibault Maurel-Oujia, Xi-Yuan +3
The goal of this numerical study is to get insight into singular solutions of the two-dimensional (2D) Euler equations for non-smooth initial data, in particular for vortex sheets.…

Neural network models for preferential concentration of particles in two-dimensional turbulence
Thibault Maurel-Oujia, Suhas S. Jain, Keigo Matsuda +3
Cluster and void formations are key processes in the dynamics of particle-laden turbulence. In this work, we assess the performance of various neural network models for synthesizin…
