Can vibrations be created due to large pressure differences in air


MattG

Question

I’m working on some designs for work and I have concerns with vibrations generated due to air running through small holes in what are effectively plates.

These plates can be assumed to be static and shouldn’t cause audible vibrations.

I’m concerned of the air moving through the holes. Due to the large pressure difference from moving through the hole can the air self generate audible vibrations?

 

Is there anything i can read up on for this? I imagine it would be similar to cavitation but without the transition from liquid to vapour.

I’m also running solidworks simulations so i can get details but i’m unsure what to look for.

 

Thanks for any help,

-Matt

Of course they can cause vibrations...it is exactly the same as a flute!  the AMPLITUDE of the vibrations, however, is going to be so low as to make them negligible!

It is likely to whistle, but the only ay it could be anything other than a minor peculiarity is if it hit a resonant frequency...which SHOULD be checked for as a matter of course... (Tacoma Narrows Bridge)...check your shell frequencies and you should be fine.
