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-

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.

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 ...

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

Effects of boundaries for high Reynolds number artificial swimmers [PDF]
Scientific ReportsThe spatial organization of active particles or swimmers may depend strongly on the nature of the interaction between the particles and the boundary. Here we use robotic fish of several centimeters dimensions that swim at high enough velocities to reach ...

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

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