Resumen de: US2024344496A1
A “strake” is a device intended to mitigate oscillations in vortex shedding over a bluff body. In a ducted turbine, wind flowing perpendicular to the central axis of the duct can propagate oscillating vortex shedding. Such oscillations can result in resonant vibrations and cause stress or damage to the turbine and support structure. A strake is a protrusion extending upward with respect to, or perpendicular to, the outer surface of the duct that causes separation of flow over the surface and prevents oscillating vortex shedding.
