Reynolds stress scaling in the near-wall region of wall-bounded flows
TLDR
In this paper, a new scaling was derived that yields a Reynolds-number independent profile for all components of the Reynolds stress in the near-wall region of wall-bounded flows, including channel, pipe and boundary layer flows.Abstract:
A new scaling is derived that yields a Reynolds-number-independent profile for all components of the Reynolds stress in the near-wall region of wall-bounded flows, including channel, pipe and boundary layer flows. The scaling demonstrates the important role played by the wall shear stress fluctuations and how the large eddies determine the Reynolds number dependence of the near-wall turbulence behaviour.read more

Reynolds number dependence of inner peak turbulence intensity in pipe flow
TL;DR: In this paper , the authors investigated the Reynolds number dependence of the inner peak turbulence intensity and found that it is very similar to that in a turbulent boundary layer (TBL), and that the slope of the outer logarithmic region in the turbulence intensity profile is twice the slope obtained from the relation between the inner peaks and the Reynolds numbers.
