An example from turbulence how not to use the invariant function method of Lie-group symmetries
Michael Frewer, George Khujadze
The recent Reply by Oberlack et al. [Phys. Rev. Lett. 130, 069403 (2023)] fails to rebut the critique that a mathematical solution method has been misapplied in their original work…

A critical examination of the conformal invariance in the statistical equations of 2D turbulent scalar fields
Michael Frewer, George Khujadze
The recent study by Waclawczyk et al. [Phys. Rev. Fluids 6, 084610 (2021)] on conformal invariance in 2D turbulence is misleading as it makes three incorrect claims that form the c…

On the use of applying Lie-group symmetry analysis to turbulent channel flow with streamwise rotation
Michael Frewer, George Khujadze
The study by Oberlack et al. (2006) consists of two main parts: a direct numerical simulation (DNS) of a turbulent plane channel flow with streamwise rotation and a preceding Lie-g…
