Title:
OBJECT SURFACE STRUCTURE FOR RESISTANCE REDUCTION/RECTIFICATION, PREPARATION METHOD AND DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/116303
Kind Code:
A1
Abstract:
An object surface structure for resistance reduction/rectification, a preparation method and a device. The object surface structure comprises: a basic surface of an object, arc bulges formed by a plurality of cambered surface-shaped bulges being distributed on the basic surface in an array manner. The arc bulges are: the cambered surfaces of rotatable objects having arc-shaped surfaces in pits on the basic surface exposed out of the pits form rotatable arc bulges; or cambered surface-shaped objects fixed on the basic surface or arc-shaped convex parts integrated with the basic surface form fixed arc bulges. The object surface structure provided with the plurality of arc bulges forms an arc bulge surface structure. The present invention reduces the resistance and friction force between an object with the surface structure and an external fluid when the object moves in the fluid, and reduces the amount and the acting force of clutter, eddy current and shock waves of the fluid on the surface of the object, so that the motion efficiency is improved, the energy consumption of corresponding advancing apparatuses is reduced, the advancing efficiency thereof is improved, the noise is reduced, the resonance is reduced, and the controllability of moving objects is improved.
