New symmetry-induced scaling laws of passive scalar transport in turbulent plane jets

H Sadeghi, M Oberlack, M Gauding - Journal of Fluid Mechanics, 2021 - cambridge.org
The primary object of this study is to derive new scaling laws for passive scalar statistical
quantities in temporally and spatially evolving plane turbulent jet flows. We apply Lie …

Validation of symmetry-induced high moment velocity and temperature scaling laws in a turbulent channel flow

F Alcántara-Ávila, LM García-Raffi, S Hoyas… - Physical Review E, 2024 - APS
The symmetry-based turbulence theory has been used to derive new scaling laws for the

Lie groups and continuum mechanics: where do we stand today?

G de Saxcé, D Razafindralandy - Comptes …, 2023 - comptes-rendus.academie-sciences …
The geometric methods have experienced a fast growth in the past few decades. In this
survey, we discuss the use of Lie groups in continuum mechanics. We address both the …

No new scaling laws of passive scalar with a constant mean gradient in decaying isotropic turbulence

M Frewer - arXiv preprint arXiv:2205.15652, 2022 - arxiv.org
In the study by Sadeghi & Oberlack [JFM 899, A10 (2020)] it is claimed that new scaling laws
are derived for the case of passive scalar dynamics under the influence of a constant mean …

On the Lie symmetries of characteristic function hierarchy in compressible turbulence

DS Praturi, D Pluemacher, M Oberlack - European Journal of …, 2023 - cambridge.org
We compute the Lie symmetries of characteristic function (CF) hierarchy of compressible
turbulence, ignoring the effects of viscosity and heat conductivity. In the probability density …
