Design method of high-fidelity non-uniform shark-imitating groove microstructure of large cooing tower fan blade

The invention relates to a design method of a high-fidelity non-uniform shark-imitating groove microstructure of a large cooing tower fan blade, in particular to a method for performing high-fidelity non-uniform shark-imitating placoid scale groove microstructure differentiation design according to different radial region linear speeds of different fan blades so as to achieve efficient bionic resistance and noise reduction and belongs to the technical field of engineering bionics. The design method has the advantages that the important fact that the Reynolds number using 'wing chord' as the characteristic length changes in the wind wheel radial direction is fully considered when resistance and noise reduction structure design is performed on the large cooing tower fan blade, the design method is scientific and reasonable compared with an existing uniform design method; compared with existing abstract and simplified low-fidelity shark-imitating resistance and noise reduction structure design, the design method
