Scale by scale analysis of magnetoconvection with uniform wall-normal and wall-parallel magnetic fields at low magnetic Reynolds number
Jake Ineson, Aleksander Dubas, Alex Skillen
Rayleigh-Bénard convection under an imposed inductionless magnetic field is analysed statistically from the perspective of single-point and multi-scale energy budgets. The data is…
Unstable magnetic reconnection self-generates turbulence
Nick Williams, Alessandro De Rosis, Alex Skillen
Magnetic reconnection and turbulence are deeply intertwined in magnetohydrodynamic flows, yet how reconnection self-generates turbulence remains unclear. Using an ensemble of high-…
Learning Temporally Consistent Turbulence Between Sparse Snapshots via Diffusion Models
Mohammed Sardar, Małgorzata J. Zimoń, Samuel Draycott +2
We investigate the statistical accuracy of temporally interpolated spatiotemporal flow sequences between sparse, decorrelated snapshots of turbulent flow fields using conditional D…
Concerning the Use of Turbulent Flow Data for Machine Learning
Mohammed Sardar, Małgorzata J. Zimoń, 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)…
Spectrally Decomposed Diffusion Models for Generative Turbulence Recovery
Mohammed Sardar, Alex Skillen, Małgorzata J. Zimoń +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…
The Propulsion Performance of Dual Heaving Foils in Tandem, with Spanwise Flexibility
Wendi Liu, Alex Skillen, Wei Wang +2
The impact of spanwise flexibility on the propulsion performance of two foils arranged in tandem and subjected to a prescribed sinusoidal heaving motion has been studied at a Reyno…
Thermal transients in a U-Bend
Alex Skillen, Małgorzata J. Zimoń, Robert Sawko +3
We study numerically the propagation of a hot thermal transient through a U-bend via an ensemble of wall-resolved large eddy simulations. Conjugate heat transfer between fluid and…
