Plenum tank stresses considerations
Plenum tank stresses considerations
(OP)
Good day,
I am currently working in a design of a plenum chamber. I am new in this topic, I would like to see your recommendations of the followings doubts that I have:
1.-This Plenum tank will have 3 outlets and 1 inlet, to calculate its stresses, can I consider it as a thin pressure vessel? I am asking this because it wont hold any gas, its purpose is just to equalize pressure in all the outlets.
2.- I want to minimize radial deformation as much as possible, what kind of elements are recommended to achieve this? (Ribs, rings, etc). And how can I obtain the radial growth?
This plenum tank will be running hot air at high pressure (above 250 psig at 1000F), if you have any other suggestion it is welcome.
Thanks in advance!

It is a 15in inner diameter with a 0.5" thickness round plenum tank.

You say that you want to minimize radial growth. Is that under pressure or does that include radial thermal expansion? Because ~16in OD made from an austenitic stainless steel is going to grow in diameter by 0.153in. Is that excessive for your application?

The problem with sloppy work is that the supply FAR EXCEEDS the demand

This part is not for an aerospace component.
The reason I want to constrain radial growth, is because that growth overstress a pipe that connects to it.
