Mathematical modelling of flows in dividing and combining flow manifold
TLDR
In this paper, a finite-difference procedure has been developed for predicting flows in dividing and combining flow manifolds, which requires the prescription of total flow rate through the header and the pressure of the surroundings where the fluid is either discharged or sucked.About:

Airflow and Cooling in a Data Center
TL;DR: In this paper, the authors deal with the distribution of airflow and the resulting cooling in a data center and explore a number of ways of controlling the airflow distribution and different strategies for doing this are considered.

Airflow distribution through perforated tiles in raised-floor data centers
TL;DR: In this paper, the effect of these parameters on the airflow distribution is studied using an idealized one-dimensional computational model, which is governed by two dimensionless parameters: one related to the pressure variation in the plenum and the other to the frictional resistance.

TL;DR: In this article, the authors address two-phase flow distribution phenomena in multiple header-tube junctions used in heat exchangers, and show that solutions which provide uniform flow distribution are very design-specific.

The effect of area ratio on the flow distribution in liquid cooling module manifolds for electronic packaging
TL;DR: In this paper, the effect of an area ratio, defined as ratio of the total channel cross-sectional area to the dividing flow header crosssectional area, on the coolant distribution in a parallel flow manifold was studied numerically for a Reynolds number of 50, a typical flow condition observed in electronic packaging.

A critical evaluation of upstream differencing applied to problems involving fluid flow
TL;DR: In this paper, the authors show that the false diffusion normally associated with upstream differences is a poor indicator of the total error in approximating the convection terms, and a new definition for false diffusion is proposed.

Flow distributions in manifolds
TL;DR: In this article, the authors present a flow model based on one-dimensional flow equations for a wide variety of combinations of channel dimensions, fluid velocity and physical properties, and pressure drop across the side ports, which are summarized by charts that permit a designer quickly to estimate the nonuniformity in the flow pattern.
