AI Technical Summary
Technical Problem
Existing turbine blades lack efficient groove structures that reduce fluid resistance and noise generation during operation, which affects energy efficiency and performance.
Method used
A groove structure is formed on the surface of turbine blades, comprising multiple intersecting grooves and lands, designed based on fluid streamlines to minimize fluid resistance and noise, using laser processing to create a riblet structure.
Benefits of technology
The riblet structure reduces fluid resistance and noise, enhancing the energy efficiency and performance of turbine blades by optimizing fluid flow dynamics.
