Performance of a high-order MPI-Kokkos accelerated fluid solver
Filipp Sporykhin, Holger Homann
This work discusses the performance of a modern numerical scheme for fluid dynamical problems on modern high-performance computing architectures. Our code implements a spatial noda…
SoAx: A generic C++ Structure of Arrays for handling Particles in HPC Codes
Holger Homann, Francois Laenen
The numerical study of physical problems often require integrating the dynamics of a large number of particles evolving according to a given set of equations. Particles are charact…
Dynamo enhancement and mode selection triggered by high magnetic permeability
Sophia Kreuzahler, Yannick Ponty, Nicolas Plihon +2
We present results from consistent dynamo simulations, where the electrically conducting and incompressible flow inside a cylinder vessel is forced by moving impellers numerically…
Effect of turbulence on collisions of dust particles with planetesimals in protoplanetary disks
H. Homann, T. Guillot, J. Bec +3
Planetesimals in gaseous protoplanetary disks may grow by collecting dust particles. Hydrodynamical studies show that small particles generally avoid collisions with the planetesim…
Abrupt growth of large aggregates by correlated coalescences in turbulent flow
Jeremie Bec, Samriddhi Sankar Ray, Ewe Wei Saw +1
Smoluchowski's coagulation kinetics is here shown to fail when the coalescing species are dilute and transported by a turbulent flow. The intermittent Lagrangian motion involves co…
Concentrations of inertial particles in the turbulent wake of an immobile sphere
Holger Homann, Jérémie Bec
Direct numerical simulations are used to study the interaction of a stream of small heavy inertial particles with the laminar and turbulent wakes of an immobile sphere facing an in…
