The Scruton number Sc is an important parameter for
vortex-induced vibration
In fluid dynamics, vortex-induced vibrations (VIV) are motions induced on bodies interacting with an external fluid flow, produced by, or the motion producing, periodic irregularities on this flow.
A classic example is the VIV of an underwater c ...
(excitation) of structures, vibrations caused by rain or wind, dry inclined
cable galloping, and wake galloping, the unstable airflow that forms around bridge cables and other cylindrically-structured buildings. It is named after Christopher "Kit" Scruton, a British industrial dynamics engineer.
