AI Technical Summary
Existing single drag reduction techniques are not effective in complex and variable flow field environments, and it is difficult to achieve the coupling of multiple drag reduction methods.
A variable-structure composite drag-reducing surface based on a biomimetic drag-reducing structure is adopted, which combines a rigid substrate, a flexible deformable layer, a hydrophobic slip layer and a metal electrolytic layer. Through the spanwise sinusoidal groove design inspired by dolphins, and by the cooperation of the fluid medium filling layer and the metal electrolytic layer, multiple drag-reducing technologies are coupled, including biomimetic structure, superhydrophobicity, flexible wall and microbubble drag reduction.
By adjusting the fluid medium filling amount and the energization of the metal electrolytic layer under different flow field conditions, the drag reduction effect can be enhanced, frictional resistance can be reduced, navigation efficiency can be improved, and the system can adapt to complex flow field environments.
