Velocity distributions in a plate heat exchanger channel
… Doppler Anemometer technique to measure the velocity distribution in a commercial plate heat exchanger is described. Detailed velocity profiles are presented and a preliminary investigation is reported on flow behaviour through a single cell in the channel matrix. The objective of the study …

Vertical Velocity Distributions in Sand -Bed Alluvial Rivers
Shear partition models of Einstein and Nelson-Smith were evaluated with the field data collected in this research. Einstein's method had an absolute average percent error of 11.3%, while the Nelson-Smith method had an absolute average percent error of 22.2% when the smaller bedforms were used as …

Empirical Constraints on O(5+) Outflows and Velocity Distributions in a Solar-Minimum Coronal Streamer
… in terms of empirical constraints on the O5+ ion velocity distributions and outflow speeds. Four conclusions result from this work: (1) our analysis shows O5+ velocity distribution anisotropy in the streamer legs and stalk and also shows that the microscopic velocity distribution (which excludes …

The velocity and directional distribution of subliming molecules
… have been obtained from this derivation of the velocity and directional distributions of subliming molecules: (1) Equations for tart velocity distributions normal and parallel to the surface as functions of temperature, and for the normal distribution, function of the potential barrier to …

Photodissociation Dynamics of Small Molecules
… used in determining the product internal state distributions. It was found that for both BrCN and cyanogen the disposal of energy into the product degrees-of-freedom is strongly influenced by the initial parent rovibrational excitation. Relative rotational state population of 0.15 for the v = 1 …

Velocity distribution prediction in rectangular and compound channels under smooth and rough flow conditions
… in river engineering require predictions of velocity distributions in single and compound open channels. In this study, velocity distributions in rectangular and compound open channels under different flow regimes, in terms of roughness and turbulence conditions, were investigated …

Potential flow solution and incompressible boundary layer for a two-dimensional cascade
… differences has been written to calculate the velocity distributions on the rotor blade of an axial-flow compressor. The shape of the blade has been approximated in two different ways employing a rather elaborate method and one whose primary goal was simplicity. The ensuing velocity …

The effects of nose and corner radii on the flow about blunt bodies at angle of attack
… bodies at angle of attack. Experimental pressure distributions were measured on a family of blunt, axisymmetric bodies which included a range of ratios of body radius to nose radius from 0 (flat face) to 0.707 and ratios of corner radius to body radius from 0 (sharp corner) to 0.4. The tests were …

Defining Stress Changes Ahead of a Tunnel Face and Design of a Data Acquisition System
… of the active face. Seismic tomography maps the velocity distributions of elastic waves traveling through a rock mass. The velocity distributions mapped in the tomograms can relate to anomalies in the rock such as fracture zones and highly concentrated stresses. In order to develop a relationship …

Flat plate turbulent boundary layer static temperature distribution with heat transfer
An expression for the static temperature-velocity distribution for a zero pressure gradient turbulent boundary layer is derived based on the differential equations for local heat transfer and shear. The present theoretical method of computation is found to give results that correspond well with …
