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.

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 ...

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 (

Reynolds number calculation and applications for curved wall jets [PDF]

INCAS Bulletin, 2014
The current paper refers to the preliminary estimation of the Reynolds number for curved wall jets. This, in turn, can be a useful tool for controlling the boundary layer mesh size near a generic curved wall which is wetted by a thin, attached jet.

Low Reynolds Number Rotor Blade Aerodynamic Analysis

MATEC Web of Conferences, 2019
Maintaining a steady hover flight in a rotorcraft usually requires high energy input. The aim of the paper is to prove that it is possible to vastly reduce energy use in a rotorcraft by reducing the disc loading.
