Group analysis, direct numerical simulation and modelling of a turbulent channel flow with streamwise rotation

Published in JFM, 2006 by Oberlack, Cabot, Pettersson-Reif & Weller. This publication is misleading and flawed. Apart from various mathematical errors, this study is altogether inconsistent in its Lie-group symmetry part. In addition it also contains several non-reproducible conclusions. All details and corrections to this flawed study are given in https://arxiv.org/abs/1609.08155 .

Conformal invariance of the zero-vorticity Lagrangian path in 2D turbulence

Published in Journal of Physics A, 2019  by Grebenev, Waclawczyk & Oberlack. This publication is seriously misleading and flawed. The conformal invariance for the Lundgren-Monin-Novikov vorticity equations cannot be confirmed, neither in the Eulerian nor in the Lagrangian framework. All details and corrections are given in  https://arxiv.org/abs/2008.11715 , and more comprehensively in  https://doi.org/10.5281/zenodo.6228153 .
