Hi guys,

Who has the experiences about calculation (checking) of the column vortex shedding? and can shed some lights here?

Though not directly involved lately here are two references that were given to me that are currently being used.

Our worst case was a the information from Meca states was tha someone put strakes on a tall slim stack without doing the calculations. The results were the same as in the video,only worst.

ASME STS-1-2000

Hi unclesyd,

If there is vortex shedding, do you know how to calculate the vibration cycles?

Thank you.
