Stack Design
The design of large stacks poses considerable engineering challenges. Vortex shedding in high winds can cause dangerous oscillations in the stack, and may lead to its collapse. The use of helical faring is common to prevent this process occurring at or close to the resonant frequency of the stack.

““Farewell to barn and stack and tree,
Farewell to Severn shore.

For I come home no more.”
