Causally coherent structures in turbulent dynamical systems
Daniele Massaro, Saleh Rezaeiravesh, Philipp Schlatter
The extraction of spatio-temporal coherence in high-dimensional, chaotic, non-linear dynamical systems, such as turbulent flows, remains a fundamental challenge in physics, mathema…
Effects of lower floating-point precision on scale-resolving numerical simulations of turbulence
Martin Karp, Ronith Stanly, Timofey Mukha +11
Modern computing clusters offer specialized hardware for reduced-precision arithmetic that can speed up the time to solution significantly. This is possible due to a decrease in da…
Robustness and uncertainty of direct numerical simulation under the influence of rounding and noise
Martin Karp, Niclas Jansson, Saleh Rezaeiravesh +2
Numerical precision in large-scale scientific computations has become an emerging topic due to recent developments in computer hardware. Lower floating point precision offers the p…
In-situ Estimation of Time-averaging Uncertainties in Turbulent Flow Simulations
Saleh Rezaeiravesh, Christian Gscheidle, Adam Peplinski +2
The statistics obtained from turbulent flow simulations are generally uncertain due to finite time averaging. The techniques available in the literature to accurately estimate thes…
Applying Bayesian Optimization with Gaussian Process Regression to Computational Fluid Dynamics Problems
Y. Morita, S. Rezaeiravesh, N. Tabatabaei +3
Bayesian optimization (BO) based on Gaussian process regression (GPR) is applied to different CFD (computational fluid dynamics) problems which can be of practical relevance. The p…
