Even distribution/dividing of single-phase fluids by symmetric bifurcation of flow channels

International Journal of Heat and Fluid Flow, 2013
Abstract This study addresses a fundamental issue of distributing a single-phase fluid flow into a number of flow channels uniformly. A basic mechanism of flow distribution is accomplished through bifurcation of channels that symmetrically split one flow channel into two downstream channels.

Measurement of core flow distribution in a research reactor using plate-type fuel assembly

, 2020
In the present study, the core flow distribution of research reactors that used a plate-type fuel was investigated by measuring the flow rates at all fuel assembly locations to determine the flow uniformity in the reactor core.

Mechanism of lateral metal flow on residual stress distribution during hot strip rolling

, 2021
During hot strip rolling, the lateral metal flow can change the longitudinal residual stress to reduce the risk of buckling deformation of the strip. The mechanism of lateral metal flow on residual stress was studied by combining a residual stress model ...

The Relation Between Evenness and Diversity

Diversity, 2010
Contrary to common belief, decomposition of diversity into independent richness and evenness components is mathematically impossible. However, richness can be decomposed into independent diversity and evenness or inequality components.

The influences of variable sectional area design on improving the hydrocarbon fuel flow distribution in parallel channels under supercritical pressure

Fuel, 2018
To help solve flow mal-distribution and cooling capacity utilization problems in parallel cooling channels of SCRamjet, the variable channel sectional area design is put forward. 3D modelling of the flow and heat transfer in multiple parallel channels is

The influences of the header geometry on hydrocarbon fuel flow distribution in compact parallel channels

Aerospace Science and Technology, 2018
Parallel cooling channels have been a commonly seen configuration in advanced aero-engines, for example, the scramjet. However, the mal-distribution of hydrocarbon fuel in cooling channels may cause waste of fuel cooling capacity and even over ...

Effect of guide strips on the distribution of threshed outputs and cleaning losses for a tangential-longitudinal flow rice combine harvester

, 2020
The transverse distribution of the threshed material in a typical tangential-longitudinal flow combine harvester is uneven and this is likely to cause local accumulation of materials on the cleaning screen.
