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 ...

Lagrangian controllability at low Reynolds number [PDF]
, 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 ...

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.

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.

Reynolds number effects on the Reynolds-stress budgets in turbulent channels [PDF]
, 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 ...

Reynolds number dependence of scalar fluctuations in a high Schmidt number turbulent jet [PDF]
, 1991 The scalar rms fluctuations in a turbulent jet were investigated experimentally, using high-resolution, laser-induced fluorescence techniques. The experiments were conducted in a high Schmidt number fluid (water), on the jet centerline, over a jet ...

Turbulence via Intermolecular Potential: Viscosity and Transition Range of the Reynolds Number
Fluids, 2023 Turbulence in fluids is an ubiquitous phenomenon, characterized by spontaneous transition of a smooth, laminar flow to rapidly changing, chaotic dynamics.

What is the Reynolds Number of the Reynolds' Layer? [PDF]
, 1999 Several authors have now suggested that some interstellar clouds above the plane of the Galaxy are interacting with the Reynolds' layer, the warm ionized gas extending well above (H~910 pc) the Galactic plane (Reynolds 1993). Characterizing the interaction between these clouds and their surroundings should be useful in understanding one source of ...

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 (
