text: Fairings can be fitted to a structure to streamline the flow past the structure, such as on an aircraft wing.
  Tall metal smokestacks or other tubular structures such as antenna masts or tethered cables can be fitted with an external corkscrew fin (a strake) to deliberately introduce turbulence, so the load is less variable and resonant load frequencies have negligible amplitudes. The effectiveness of helical strakes for reducing vortex induced vibration was discovered in 1957 by Christopher Scruton and D. E. J. Walshe at the National Physics Laboratory in Great Britain. They are therefore often described as Scruton strakes. For maximum effectiveness in suppression of vortices caused by air flow, each fin or strake should have a height of about 10 percent of the cylinder diameter. The pitch of each fin should be approximately 5 times the cylinder diameter.
  A tuned mass damper can be used to mitigate vortex shedding in stacks and chimneys.
  A Stockbridge damper is used to mitigate aeolian vibrations caused by vortex shedding on overhead power lines.
