Electron columns confined magnetically in vacuum evolve in ðr; hÞ as N 10 field-aligned rods of charge, or point vortices. Neglecting discreteness, the column evolves as would vorticity in an inviscid, incompressible fluid, governed by the Euler equations. The macroscopic flow dynamics is readily imaged, including effects such as surface waves and inviscid damping, two vortex merger, and gradie...

Two-dimensional protein crystallization on lipid monolayers at a quiescent air/water interface is now a well-established process, but it only operates under a very restricted set of conditions and on a very slow time scale. We have recently been able to significantly extend the conditions under which the proteins will crystalize as well as speed up the process by subjecting the interface to a s...

We study diffusiophoretic exclusion zone (EZ) formation in rectangular channel flow, driven by CO 2 dissolution from one side wall. By using a similarity transform and considering the flow structure, we obtain relation between EZ wall shear rate.

We present an analysis of the accuracy of the lattice Boltzmann BGK (LBGK) method in simulating pulsatile blood flow in a model of the Human Abdominal Aorta. The flow is driven by a systolic pressure cycle. As a benchmark, we consider fully developed pulsatile flow in a straight tube. We compare velocity profiles and shear stress to the analytical Womersley solutions. The accuracy of the bounce...

We experimentally investigate the drag-reduced channel flow of an inelastic, shear-thinning rigid polymer solution. Particle image velocimetry and shear-viscosity measurements are used to obtain instantaneous distributions shear viscosity within turbulent domain. elucidate that drag reduction for polymers is primarily driven by a thin lubricating layer consists low-viscosity fluid near wall.

In this paper, some experiments of liquid dispersion flow driven by explosion in vertical plane were carried out using a liquid explosive dispersion device with film cylindrical constraints. The separated time series describing the breakup shape and dispersion process of liquid were recorded with high speed CMOS camera. The experimental results were analyzed and some essential characteristics o...

We discuss pressure-driven channel flow for a model of shear-thinning glass-forming fluids, employing a modified lattice-Boltzmann (LB) simulation scheme. The model is motivated by a recent microscopic approach to the nonlinear rheology of colloidal suspensions and captures a nonvanishing dynamical yield stress and the appearance of normal-stress differences and a flow-induced pressure contribu...

We investigate the linear stability of a double-diffusively stratified, inflectional shear flow. Double-diffusive stratification has little effect on shear instability except when the density ratio Rρ is close to unity. Double-diffusive instabilities have significant growth rates and can represent the fastest growing mode even in the presence of inflectionally unstable shear with low Richardson...

This paper presents unsteady computational simulation results and supporting experimental evidence that show a certain fundamental feature of a purely shear driven annular/stratified internal condensing flow with respect to its sensitivity to boundary conditions. This feature is termed “elliptic sensitivity.” Shear driven condensing flows occur in 0g, horizontal channels, and micro-meter scale ...
