Side branch resonance excited by flow in the main pipe
Side branch resonance excited by flow in the main pipe
(OP)
Hi,
I have a side branch on my 6"NB pipe which is 42.9mm i/d and 300mm long, it is terminated in a closed valve.
It is a natural gas pipe operating at 40 Barg / 15 deg C.
I am concerned that there may be some critical flow velocities in the 6"NB pipe that would cause a resonance in the side branch to give me a whistle effect.
Is there a way to work this out ?
Any help or references would be appreciated.

I have found a paper called
Strouhal numbers of flow-excited acoustic resonance of closed side branches, Journal of Fluids and Structure, Ziada, S and Shine, S., 1999
It gives me what I need.
