Coherence does not always imply causality in wall-bounded turbulence
Peng E S Chen, Javier Jimenez
Compact structures of intense tangential Reynolds stress (Q events) are well-known components of wall-bounded turbulence, and have been shown to be coherent because they approximat…

The eddies are attached, but it is all right
Javier Jiménez
The behavior of velocity fluctuations near a wall has long fascinated the turbulence community, because the prevalent theoretical framework of an attached-eddy hierarchy appears to…

Causal features in turbulent channel flow
Kosuke Osawa, Javier Jimenez
The causal relevance of local flow conditions in wall-bounded turbulence is analysed using ensembles of interventional experiments in which the effect of perturbing the flow within…
