On the use of the Stokes number to explain frictional tidal dynamics and water column structure in shelf seas [PDF]
In recent years coastal oceanographers have suggested using the "Strouhal" number or its inverse, the "Stokes" number, to describe the effect of bottom boundary layer turbulence on the vertical structure of both density and currents. These are defined as

Vorticity moments in four numerical simulations of the 3D Navier–Stokes equations [PDF]
The issue of intermittency in numerical solutions of the 3D Navier–Stokes equations on a periodic box [0,L]3 is addressed through four sets of numerical simulations that calculate a new set of variables defined by Dm(t)=(ϖ−10Ωm)αm for 1≤m≤∞ where αm=2m ...

A sequential regularization method for time-dependent incompressible Navier--Stokes equations [PDF]
The objective of the paper is to present a method, called the sequential regularization method (SRM), for the nonstationary incompressible Navier--Stokes equations from the viewpoint of regularization of differential-algebraic equations (DAEs), and to ...

Visualization of synthetic jets at higher Stokes numbers [PDF]
Visualization of synthetic jets at higher Stokes numbers (S = 90 and 127) by the phase-locked smoke-wire technique is presented and discussed. The working fluid is air. The Reynolds numbers are quantified using hot-wire anemometry. Although our method of visualization essentially provides only qualitative results, the present study also demonstrates ...

A regime map for dry powder coating: the influence of material properties and process parameters
A numerical study is carried out to investigate the combined influence of material properties and process parameters on coating quality in a high shear mixer (specifically an FT4 Powder Rheometer) to construct a regime map.

Distribution of Particles and Bubbles in Turbulence at a Small Stokes Number [PDF]
The inertia of particles driven by the turbulent flow of the surrounding fluid makes them prefer certain regions of the flow. The heavy particles lag behind the flow and tend to accumulate in the regions with less vorticity, while the light particles do the opposite.

Collision and Coagulation in the Infinite-Stokes-Number Regime [PDF]
This paper presents a theoretical description of collision and coagulation in the infinite-Stokes-number limit where particle motions are only weakly correlated with the fluid. A methodology for predicting the collision frequency and the particle mean energy is developed based on the assumption of a Maxwellian velocity distribution.
