Oscillatory Electrohydrodynamic Gas Flows

Journal of Fluids Engineering, 1995
Prior numerical solutions of electrohydrodynamic flows in a positive-corona, wire-plate electrostatic precipitator are extended to reveal steady-periodic electrohydrodynamic flows. Previously, only steady solutions were reported. The present study includes results for flows with Reynolds numbers from 0 to 4800 and with dimensionless electric number ...

Oscillatory cross‐flow electrophoresis

AIChE Journal, 1991
AbstractElectrophoresis is a useful analytic technique for the separation of proteins and other large molecules, but has proven resistant to scale‐up to production levels. In this article we describe a new technique that permits the use of much greater feed rates than possible in a conventional electrophoresis unit.

Oscillatory Flow Theory

2010
The pressure-flow relation for steady flow, where only frictional losses are considered (resistance, law of Poiseuille), and the relation between oscillatory or pulsatile pressure and flow when only blood mass (inertance) is taken into consideration, are simplifications of reality.

Oscillatory buoyant thermocapillary flow

Physics of Fluids, 1994
A computational study of the character and stability of two-dimensional buoyant thermocapillary flows, valid to leading order in capillary number (Ca), is conducted in the Grashof number (Gr), Reynolds number (Re), aspect ratio, and Prandtl number (Pr) parameter space. Calculations of thermocapillary convection for low Pr fluids have generally produced

Oscillatory Granular Flows

1998
An experimental device has been used to examine the behavior of granular materials under vertical, horizontal and combined bi-axial vibrations. Different container geometries were used with glass spheres, millet and lentils as granular media. Frontal and lateral visualization of the flow was made possible with high-speed video cameras.

Regime of Oscillatory Flow

Journal of Waterway, Port, Coastal, and Ocean Engineering, 1985
A regime of flow is defined as the transition from laminar to turbulent flow which is an inception of turbulence in the flow field. Knowledge of flow regime provides useful information for quantitative description of flow and its analysis. It also serves as the lower limit of sediment transport.

Transient and Oscillatory Granular Shear Flow

Physical Review Letters, 2004
The forces and particle motion during transient and oscillatory shear of granular material are investigated experimentally. In a shear cell of Taylor-Couette-type we find that how a granular shear flow starts depends strongly on the prior shear direction.

Oscillatory stokes flow in two dimensions

Mechanics Research Communications, 1994
Plane oscillatory Stokes flow has been discussed using circular harmonics. The solutions for (i) longitudinal oscillations of a circular cylinder in an unbounded flow, and (ii) oscillational shear flow past a circular cylinder have been obtained. The stream function in (i) can be interpreted as a combination of Stokeslet and potential doublet, and in ...

Concentration effects in oscillatory blood flow

Biorheology, 1969
A continuum model of fluid suspensions is applied to the problem of unsteady tube flow of a fluid in which deformations of suspended particles are negligible. An expression is obtained for the volumetric flow rate as a function of suspension concentration.
