Spectrally Decomposed Diffusion Models for Generative Turbulence Recovery
Mohammed Sardar, Alex Skillen, MaÅgorzata J. ZimoÅ +2
We investigate the statistical recovery of missing physics and turbulent phenomena in fluid flows using generative machine learning. Here we develop a two-stage super-resolution me…

Concerning the Use of Turbulent Flow Data for Machine Learning
Mohammed Sardar, MaÅgorzata J. ZimoÅ, Samuel Draycott +2
This article describes some common issues encountered in the use of Direct Numerical Simulation (DNS) turbulent flow data for machine learning. We focus on two specific issues; 1)…
