This article proposes a definition of the Reynolds number in a form, which is applicable point-wise to an entire volume of fluid. This dimensionless number is termed a local Reynolds number in the article.

D4 Reynolds Number Corrections We explain why the ratio of inertia to friction forces, as characterized by the Reynolds number, influence gas turbine performance. We describe how the use of the Reynolds Number Index can simplify performance calculations. How to correlate Reynolds number corrections to real data is illustrated through use of a pipe flow

Reynolds number scaling of the peak turbulence intensity in wall flows
Journal of Fluid Mechanics, 2020The celebrated wall-scaling works for many statistical averages in turbulent flows near smooth walls, but the streamwise velocity fluctuation, $u^{\prime }$, is thought to be among the few exceptions.

The onset of dynamic stall at a high, transitional Reynolds number
Journal of Fluid Mechanics, 2018Dynamic stall due to a ramp-type pitching motion is investigated on the NACA 0012 airfoil at chord Reynolds number of $Re_{c}=1.0\times 10^{6}$ through the use of wall-resolved large-eddy simulation.

Uniqueness and the Cell Reynolds Number
SIAM Journal on Numerical Analysis, 1980Using some results from the theory of M-functions, we show how uniqueness and multiplicity of solutions for three finite-difference approximations of the steady Burgers equation are related to the cell Reynolds number.

Physical Review E, 2015
To generalize simple bead-linker model of swimmers to higher dimensions and to demonstrate the chemotaxis ability of such swimmers, here we introduce a low-Reynolds predator, using a two-dimensional triangular bead-spring model. Two-state linkers as mechanochemical enzymes expand as a result of interaction with particular activator substances in the ...

Intermittency and Reynolds number
Physics of Fluids, 1998Hot wire measurements of longitudinal and transverse increments are performed in three different types of flows on a large range of Reynolds numbers (100≲Rλ≲3000). An improved technique based on cumulant expansion of velocity structure functions is used to estimate the spreading of the pdfs and to study their scaling properties in the inertial range ...
