Holography of the QGP Reynolds number
Nuclear Physics B, 2017 The viscosity of the Quark–Gluon Plasma (QGP) is usually described holographically by the entropy-normalized dynamic viscosity η/s. However, other measures of viscosity, such as the kinematic viscosity ν and the Reynolds number Re, are often useful, and ...

Turbulence Model Selection for Low Reynolds Number Flows. [PDF]
PLoS ONE, 2016 One of the major flow phenomena associated with low Reynolds number flow is the formation of separation bubbles on an airfoil's surface. NACA4415 airfoil is commonly used in wind turbines and UAV applications.

Swimming at low Reynolds number [PDF]
ESAIM: Proceedings and Surveys, 2020 We address the swimming problem at low Reynolds number. This regime, which is typically used for micro-swimmers, is described by Stokes equations. We couple a PDE solver of Stokes equations, derived from the Feel++ finite elements library, to a quaternion-

Life at low Reynolds number [PDF]
AIP Conference Proceedings, 1976 E d i t o r’s note: This is a reprint (slightly edited) of a paper of the same title that appeared in the book Physics and Our World: A Symposium in Honor of Victor F. Weisskopf, published by the American Institute of Physics (1976). The personal tone of the original talk has been preserved in the paper, which was itself a slightly edited transcript of

Population Dynamics At High Reynolds Number [PDF]
Physical Review Letters, 2010 We study the statistical properties of population dynamics evolving in a realistic two-dimensional compressible turbulent velocity field. We show that the interplay between turbulent dynamics and population growth and saturation leads to quasi-localization and a remarkable reduction in the carrying capacity. The statistical properties of the population

Low Reynolds Number Swimming Near Interfaces in Multi-Fluid Media [PDF]
Applied Sciences, 2021 Microorganisms often swim within heterogeneous fluid media composed of multiple materials with very different properties. The swimming speed is greatly affected by the composition and rheology of the fluidic environment.

Lagrangian controllability at low Reynolds number [PDF]
ESAIM: Control, Optimisation and Calculus of Variations, 2016 In this paper, we establish a result of Lagrangian controllability for a fluid at low Reynolds number, driven by the stationary Stokes equation. This amounts to the possibility of displacing a part of a fluid from one zone to another by suitably using a boundary control.

Numerical study of turbulent separation bubbles with varying pressure gradient and Reynolds number. [PDF]
J Fluid Mech, 2018 A family of cases each containing a small separation bubble is treated by direct numerical simulation (DNS), varying two parameters: the severity of the pressure gradients, generated by suction and blowing across the opposite boundary, and the Reynolds ...

Reynolds number effects on the Reynolds-stress budgets in turbulent channels [PDF]
Physics of Fluids, 2008 Budgets for the nonzero components of the Reynolds-stress tensor are presented for numerical channels with Reynolds numbers in the range Reτ=180–2000. The scaling of the different terms is discussed, both above and within the buffer and viscous layers. Above x2+≈150, most budget components scale reasonably well with uτ3/h, but the scaling with uτ4/ν is

Low-Reynolds-number swimming in gels [PDF]
EPL (Europhysics Letters), 2010 Many microorganisms swim through gels, materials with nonzero zero-frequency elastic shear modulus, such as mucus. Biological gels are typically heterogeneous, containing both a structural scaffold (network) and a fluid solvent. We analyze the swimming of an infinite sheet undergoing transverse traveling wave deformations in the "two-fluid" model of a ...
