Enclosure structure, and aerodynamic configuration adjuster arranged on outer surface of same

Abstract

An enclosure structure, and an aerodynamic configuration adjuster arranged on an outer surface of same are provided. The aerodynamic configuration adjuster is of a grid structure capable of surrounding the enclosure structure, and the grid structure comprises a plurality of grid cells, at least some of grid cells have bevel edges, and the attack angle of a fluid is changed when the fluid passes over the bevel edges. The aerodynamic configuration adjuster changes the aerodynamic configuration of the fluid, and thus the resistance coefficient becomes smaller such that a pressure differential between the pressures at a incident flow surface and a back surface of the enclosure structure is reduced, thereby reducing a forward resistance; and in addition, due to a smaller resistance coefficient, the amplitude of a transverse vortex-induced resonance can also be reduced, thereby reducing vibration.
