Effect of Reynolds Number on the Stokes Number of Cyclones

Aerosol Science and Technology, 1993
By using dimensional analysis, the Stokes number based on the cut diameter was predicted to be a function of the Reynolds number and the geometry of the cyclone. Data from various investigators were plotted versus the Reynolds number. At lower Reynolds numbers, the Stokes number decreased with increasing Reynolds number.

Reynolds number dependence of isotropic Navier-Stokes turbulence

Physical Review Letters, 1993
Reynolds number dependence of turbulence energy spectra and higher-order moments of velocity differences is explored by means of numerical integrations of the incompressible Navier-Stokes equation. The simulations have spatial resolutions up to ${512}^{3}$ and cover the range 15\ensuremath{\le}${\mathit{R}}_{\ensuremath{\lambda}}$\ensuremath{\le}200 ...

On the instability of Stokes layers at high Reynolds numbers

Journal of Fluid Mechanics, 2003
The inviscid instability of Stokes layers is investigated. The Stokes layer is shown to support inviscid Floquet modes at sufficiently high values of the disturbance wavenumbers. Other non-Floquet modes are investigated and are shown to be the likely cause for instability in Stokes layers.

Evaluation of the Nusselt number for a fluid sphere in Stokes flow

Physics of Fluids, 2022
The Nusselt number Nu is evaluated for an isothermal fluid sphere immersed in a Stokes flow. The dimensionless convective-diffusive conservation equation is solved asymptotically for the case where the Peclet number based on the sphere radius, ε, is small relative to unity. The Nusselt number is evaluated by integrating the derivative of the asymptotic

Low-Mach-number asymptotics of the Navier-Stokes equations

Journal of Engineering Mathematics, 1998
The author uses asymptotic analysis to give insight into the compressible Navier-Stokes equations at low Mach number, when slow flow is affected by acoustic effects in a bounded region over a long time.

Minimum number of modulated Stokes parameters in Young’s interference experiment

Journal of Optics A: Pure and Applied Optics, 2008
The contrast parameters associated with the generalized Stokes vector in a Young's interference experiment are analyzed. It is shown that there are two unitary transformations that can be applied to the electric fields so that a partially polarized light can be described with no more than two non-zero generalized Stokes parameters. Furthermore, general

UNSTEADY SEPARATION FOR HIGH REYNOLDS NUMBERS NAVIER-STOKES SOLUTIONS

Waves and Stability in Continuous Media, 2010
In this paper we compute the numerical solutions of Navier-Stokes equations in the case of the two dimensional disk impulsively started in a uniform back- ground flow. We shall solve the Navier-Stokes equations (for different Reynolds numbers ranging from 1.5 · 10^3 up to 10^5 ) with a fully spectral numerical scheme.
