PAINT: Parallel-in-time Neural Twins for Dynamical System Reconstruction
Andreas Radler, Vincent Seyfried, Johannes Brandstetter +1
Neural surrogates have shown great potential in simulating dynamical systems, while offering real-time capabilities. We envision Neural Twins as a progression of neural surrogates,…
NeuralDEM -- Real-time Simulation of Industrial Particulate Flows
Benedikt Alkin, Tobias Kronlachner, Samuele Papa +3
Advancements in computing power have made it possible to numerically simulate large-scale fluid-mechanical and/or particulate systems, many of which are integral to core industrial…
Data-assisted, physics-informed propagators for recurrent flows
Thomas Lichtenegger
A novel approach to simulate dynamic, recurrent flows with very large time steps is presented. Data-driven forecasts based on the method of analogues are made employing a set of pr…
Extremely fast simulations of heat transfer in fluidized beds
T. Lichtenegger, S. Pirker
Besides their huge technological importance, fluidized beds have attracted a large amount of research because they are perfect playgrounds to investigate highly dynamic particulate…
Adaptive coarse-graining for large-scale DEM simulations
Daniel Queteschiner, Thomas Lichtenegger, Simon Schneiderbauer +1
The large time and length scales and, not least, the vast number of particles involved in industrial-scale simulations inflate the computational costs of the Discrete Element Metho…
Recurrence CFD - a novel approach to simulate multiphase flows with strongly separated time scales
Thomas Lichtenegger, Stefan Pirker
Classical Computational Fluid Dynamics (CFD) of long-time processes with strongly separated time scales is computationally extremely demanding if not impossible. Consequently, the…
Superfluid 4He dynamics beyond quasiparticle excitations
K. Beauvois, C. E. Campbell, J. Dawidowski +7
The dynamics of superfluid 4He at and above the Landau quasiparticle regime is investigated by high precision inelastic neutron scattering measurements of the dynamic structure fac…
Correlations in the low-density Fermi gas: Fermi-Liquid state, Dimerization, and BCS Pairing
H. H. Fan, E. Krotscheck, T. Lichtenegger +2
We present ground state calculations for low-density Fermi gases described by two model interactions, an attractive square-well potential and a Lennard-Jones potential, of varying…
Dynamic many-body theory: Dynamic structure factor of two-dimensional liquid He
Eckhard Krotscheck, Thomas Lichtenegger
We calculate the dynamic structure function of two-dimensional liquid He at zero temperature employing a quantitative multi-particle fluctuations approach up to infinite order.…
Dynamic structure function of a cold Fermi gas at unitarity
G. E. Astrakharchik, J. Boronat, E. Krotscheck +1
We present a theoretical study of the dynamic structure function of a resonantly interacting two-component Fermi gas at zero temperature. Our approach is based on dynamic many-body…
