Abstract
An enclosure with a vortex-induced vibration suppression function and a method for suppressing vortex-induced vibration are provided. The enclosure is provided with suction through holes extending through a peripheral wall thereof, the suction through holes are distributed in a circumferential direction of the enclosure. The enclosure is further provided with a suction apparatus, and the suction apparatus can perform suctioning to the suction through holes from outside to inside, to restrain a boundary layer at an outer surface of the enclosure from being detached from the outer surface. By the suctioning, the boundary layer can be 'adsorbed' on the outer surface of the tower, thereby restraining or directly preventing the boundary layer from being detached from the outer surface of the tower, and reducing or eliminating the cause of the vertex-induced vibration.
