Velocity Profiles In Perforated Completions

Journal of Canadian Petroleum Technology, 1991
Abstract The productivity of perforated completions is greatly reduced when fines ace mobilized causing particles to plug pore throats within a formation. Even in clean sands, relatively large quantities of particulate matter are present Mobilization of these fines occurs as fluid velocities exceed critical levels ...

Similarity of the Velocity Profile

2014
Abstract : A new approach to study similarity of the velocity profile of the 2-D wall-bound boundary layer flow is presented. The approach is based on a simple concept; the area under a set of scaled velocity profile curves that show similarity behavior must be equal.

Electroosmotic velocity profiles in microchannels

Colloids and Surfaces A: Physicochemical and Engineering Aspects, 2003
Electroosmotic flows in microchannels of circular and square cross-sections with a range of hydraulic diameters are investigated experimentally. Velocity profiles at the mid-planes of the channels are obtained using a caged-dye based technique with a high degree of resolution in the bulk and near the channel walls.

VELOCITY PROFILES WITH SUSPENDED SEDIMENT

Journal of Hydraulic Research, 1981
Analysis of velocity profiles plotted in defect form indicates that the Karman coefficient is independent of the amount of suspended sediment in an open channel flow.

On the inviscid instability of the hyperbolictangent velocity profile

Journal of Fluid Mechanics, 1964
The Rayleigh stability equation of inviscid linearized stability theory was integrated numerically for amplified disturbances of the hyperbolic-tangent velocity profile. The evaluation of the eigenvalues and eigenfunctions is followed by a discussion of the streamline pattern of the disturbed flow.

[Velocity profiles in the microvessels dependent on the velocity and concentration of erythrocytes].

Fiziologicheskii zhurnal SSSR imeni I. M. Sechenova, 1983
Distribution of velocities of erythrocytes dependent upon their distance from the vascular axis were studied in 25-40 mu large microvessels of the frog mesentery. The method of in vivo cinemicrography with subsequent analysis revealed that with a mean axial velocity of blood flow higher than 0.3-0.4 mm/sec the velocity profile was parabolic, similar to

Acoustic Velocity Profiling in SYNOP.

1996
Abstract : The observational program in SYNOP consisted of three primary moored instrument arrays deployed in the Gulf Stream between Cape Hatteras and 55 deg W, complemented by regional and process-oriented studies using acoustically tracked floats and shipboard observations.

The Production of Peak Velocity Profiles

The Journal of the Royal Aeronautical Society, 1961
In the technical note in the August JOURNAL by Morgan and Saunders the values given in the last column of Table I on p. 572 are actually the square roots of the open area ratio.
