The European Physical Journal E, 2023 Lift forces are widespread in hydrodynamics. These are typically observed for big and fast objects, and are often associated with a combination of fluid inertia (i.e. large Reynolds numbers) and specific symmetry-breaking mechanisms. In contrast, the properties of viscosity-dominated (i.e.

A squirmer across Reynolds numbers [PDF]
Journal of Fluid Mechanics, 2016 The self-propulsion of a spherical squirmer – a model swimming organism that achieves locomotion via steady tangential movement of its surface – is quantified across the transition from viscously to inertially dominated flow. Specifically, the flow around a squirmer is computed for Reynolds numbers ($Re$) between 0.01 and 1000 by numerical solution 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

Analysis of low Reynolds number flow past Gurney flap [PDF]
INCAS Bulletin, 2010 The trailing edge region of a single element wing fitted with Gurney flap at low Reynoldsnumbers has been studied.The complex flow separation phenomena on airfoils with Gurney flap at low Reynolds numbershave some specific features as the separation on ...

Reynolds-number dependence of turbulence enhancement on collision growth [PDF]
Atmospheric Chemistry and Physics, 2016 This study investigates the Reynolds-number dependence of turbulence enhancement on the collision growth of cloud droplets. The Onishi turbulent coagulation kernel proposed in Onishi et al.

Biotechnology at low Reynolds numbers
Biophysical Journal, 1996 The shrinking of liquid handling systems to the micron and submicron size range entails moving into the area of small Reynolds numbers. The fluid dynamics in this regime are very different from the macroscale. We present an intuitive explanation of how the different physics of small Reynolds numbers flow, along with microscopic sizes, can influence ...

High-Reynolds-Number Flow past a Pipe
Journal of Fluid Science and Technology, 2013 The present aim is to reveal the flow past a pipe which is immersed parallel to the mainstream at high Reynolds numbers. In a wind tunnel, we carry out (1) base-pressure measurements, (2) velocity-fluctuation measurements using a hot-wire anemometer and (

Plunging Airfoil: Reynolds Number and Angle of Attack Effects
Aerospace, 2021 Natural flight has consistently been the wellspring of many creative minds, yet recreating the propulsive systems of natural flyers is quite hard and challenging.
