What is the frequency of axial flow induced vibration in bellows
What is the frequency of axial flow induced vibration in bellows
(OP)
Fuel is flowing in a piping system passes through bellows. Does this induces any vibrations in the bellows?.If Yes what will be the frequency of the excitation. The bellows upstream has a valve and down stream is a T joint.The flow velocity is just around sonic speed.
Thanks
Thanks





RE: What is the frequency of axial flow induced vibration in bellows
I would say that, if the vibration is caused by the fluid acting directly on the bellows, it would be a very difficult thing to calculate, especially if it involves turbulence. If you can identify the major mode shape using high speed photography, and its a relatively simple mode, the natural frequency might very roughly correspond to that of a beam with a distributed mass (the fuel fluid), where the axial and/or bending stiffness of the beam is equated to the matching stiffness of the empty bellows - but its a long shot.

Thanks for the reply, I have the test measured data.This is a problem faced in power system fuel line. The vibration definatly stops if the fuel is cut off. But I was curios to calculate the frequency,by some equations.
Thanks
