Three-sphere swimmer in two dimensions at low Reynolds number condition [PDF]

open access: yesمهندسی مکانیک شریف, 2022
Being widely ubiquitous in fluidic mediums from aquatic environments to bodies, for the sake of their mobility, microorganisms, such as bacteria and motile cells, make use of particular swimming strategies that are counter-intuitive to that of our daily ...

Swimming at low Reynolds number [PDF]

open access: yesESAIM: 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-

Reynolds stress scaling in the near-wall region [PDF]

open access: yesJournal of Fluid Mechanics, 926, p.A31, 2021, 2021
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. 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 ...

Flow around an Oscillating Cylinder at Low Reynolds Number with Forced Convection: Effect of Corner Radius and Reynolds Number

open access: yesEnergies, 2022
This numerical study investigated the flow-induced vibration (FIV) on non-heated and heated cylinders with different normalized corner radii (r*) at different Reynolds numbers (Re).

Vortex-induced vibration of cylinder under sub-critical Reynolds number

open access: yesZhongguo Jianchuan Yanjiu, 2022
ObjectiveIn order to achieve the accurate prediction of the amplitude response of a vortex-induced vibrating cylinder under the sub-critical Reynolds number, a method for establishing a Cl-A/D (lift coefficient-amplitude ratio)model of the forced ...

Turbulence Model Selection for Low Reynolds Number Flows. [PDF]

open access: yesPLoS 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.

Competing flow and collision effects in a monodispersed liquid-solid fluidized bed at a moderate Archimedes number [PDF]

open access: yesJournal of Fluid Mechanics, 927 (2021), A28, 2021
We study the effects of fluid-particle and particle-particle interactions in a three-dimensional monodispersed reactor with unstable fluidization. Simulations were conducted using the Immersed Boundary Method (IBM) for particle Reynolds numbers of 20-70 with an Archimedes number of 23600.

Bifurcation aspect of wide-gap spherical Couette flow emphasizing polygonal coherence and wave numbers observed over transitional Reynolds numbers [PDF]

open access: yes, 2021
This study numerically investigates the bifurcation aspect of the wide-gap spherical Couette flow (SCF), with an emphasis on the competition among polygonal coherence with different wave numbers observed over transitional Reynolds numbers. Focusing on a representative case, the half-radius ratio, we confirm that the axisymmetric state becomes unstable ...

Holography of the QGP Reynolds number

open access: yesNuclear 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 via Intermolecular Potential: Viscosity and Transition Range of the Reynolds Number

open access: yesFluids, 2023
Turbulence in fluids is an ubiquitous phenomenon, characterized by spontaneous transition of a smooth, laminar flow to rapidly changing, chaotic dynamics.
