Lift at low Reynolds number [PDF]
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.

High–Reynolds Number Taylor-Couette Turbulence [PDF]
Annual Review of Fluid Mechanics, 2016 Taylor-Couette flow, the flow between two coaxial co- or counter-rotating cylinders, is one of the paradigmatic systems in the physics of fluids. The (dimensionless) control parameters are the Reynolds numbers of the inner and outer cylinders, the ratio of the cylinder radii, and the aspect ratio.

Passive scalars in turbulent channel flow at high Reynolds number [PDF]
Journal of Fluid Mechanics, 2016 We study passive scalars in turbulent plane channels at computationally high Reynolds number, thus allowing us to observe previously unnoticed effects.

Towards the definition of a benchmark for low Reynolds number propeller aeroacoustics
Journal of Physics: Conference Series, 2021 Experimental and numerical results of a propeller of 0.3 m diameter operated in quiescent standard ambient conditions at 5000 RPM and axial velocity ranging from 0 to 20 m/s and advance ratio ranging from 0 to 0.8 are presented as a preliminary step ...

Processes, 2022 In recent years, there has been an increased interest in the old NACA four-digit series when designing wind turbines or small aircraft. One of the airfoils frequently used for this purpose is the NACA 0018 profile. However, since 1933, for over 70 years,

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 ...

Spectral analysis of the budget equation in turbulent channel flows at high Reynolds number [PDF]
Journal of Fluid Mechanics, 2018 The transport equations for the variances of the velocity components are investigated using data from direct numerical simulations of incompressible channel flows at friction Reynolds number ( $Re_{\unicode[STIX]{x1D70F}}$ ) up to $Re_{\unicode[STIX ...

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 ...
