Abstract

See full text

An enclosure having an outer surface with a vortex-induced vibration suppression function is provided. The outer surface of the enclosure is provided with a plurality of annular recesses surrounding the enclosure, such that alternately concave and convex annular recesses and annular bosses configured for disrupting a boundary layer of a laminar flow are formed on the outer surface of the enclosure. An outer surface of the annular boss is provided with a plurality of air guiding grooves, and the plurality of air guiding grooves are distributed in a circumferential direction of the annular boss. The air guiding grooves are inclined upward or downward, such that part of an upwind incoming flow flowing to the annular boss can be guided into the annular recesses adjacent to the annular boss via the air guiding grooves. With the convex-concave outer surface, the cause of formation of the vortex-induced vibration can be prevented.
