[HTML][HTML] Chaotic measures as an alternative to spectral measures for analysing turbulent flow

RDJG Ho, D Clark, A Berera - Atmosphere, 2024 - mdpi.com
Turbulence has associated chaotic features. In the past couple of decades, there has been
growing interest in the study of these features as an alternative means of understanding …

Chaos and information in two-dimensional turbulence

D Clark, L Tarra, A Berera - Physical Review Fluids, 2020 - APS
By performing a large number of fully resolved simulations of incompressible homogeneous
and isotropic two-dimensional turbulence, we study the scaling behavior of the maximal …

Critical transition to a non-chaotic regime in isotropic turbulence

D Clark, A Armua, RDJG Ho, A Berera - Journal of Fluid Mechanics, 2022 - cambridge.org
We study the properties of homogeneous and isotropic turbulence in higher spatial
dimensions through the lens of chaos and predictability using numerical simulations. We …

Effect of spatial dimensionality on the chaotic properties of turbulent flow

D Clark - 2022 - era.ed.ac.uk
The phenomenon of fluid turbulence is found almost universally in the world around us,
however, there is still much that is not understood about the underlying physics. What is …
