Manifold Design Guidelines
Manifold Design Guidelines
(OP)
I am looking for all the resources I can gather on how to design a manifold that will evenly distribute flow (air in my case but for any fluid in general) from a header pipe to several branch lines. Perry's devotes about 2 pages to the design of a perforated distributor. It's useful information but I need more and web searches are coming up empty for me. Any suggestions or stories of personal experience?

A science citation search of newer articles that reference these papers may provide more modern techniques, such as using FLUENT etc 3D CFD to simulate the flow in the headers.

Equalized flow splitting? Could you please elaborate?
RE: Manifold Design Guidelines
"Equalized flow splitting"-setting up pipe layouts so that flow is equalized in each branch. For example, three branch, one header three seperate branchs that are identical so that pressure drop is the same. Four or more branches, Main hdr, two branches, then two more branches on each of the first two branches-piping arrangements identical in order to equalize pressure drop the branch arrangements and so equalize flow.
three branch: | | |
| | | all branches require identical
Flow >____________ layouts and fittingw to
equalize pressure
drops
four or more branchs: | | | |
| | | |
_____ _____
| |
| |
Flow >_____________________
I hope this primitive sketch gives you the picture and idea of how to set up 'equalized flow splittting & distribution.
RE: Manifold Design Guidelines
I see now, thank you. Here is the real problem we a tackling at my company. We need to pump a gas through 10 separate lines from a single pump. Each line is 1/8 inch ID and 3/16 inch OD. The outlet of the pump is 1/4 NPT. Volume to be pumped through the main line is 5 liters/min. I need to figure out how to distribute the flow.
