Explaining the Vortex Shedding Phenomenon

When designing stacks one of the things that IVI takes into account is the vortex shedding phenomenon that occurs naturally due to wind loads. IVI takes into account the vortex shedding in the design phase. So any possible failures such as base plate or anchorage may not be an issue in the future.

Overcoming Vortex Shedding

There are a couple methods to overcome vortex shedding. One of them may be helical strakes. They’re easy to design. They are most common as well. Another method is liquid tuned dampers. These aren’t very common, but they can also be used for large diameter stacks. And finally another option is a tuned mast damper. These provide the most dampening effect for a larger diameter stack. They can be costly however you can visually see them work as they’re inoperation.
