超疏水表面减阻技术研究进展
Research Progress on Drag Reduction Technology for Super-hydrophobic Surfaces
摘要
Abstract
The wettability,influencing factors of drag reduction performance,drag reduction mechanism,and preparation method of super-hydrophobic surfaces are summarized,and the key research directions that should be paid attention to in the future are put for-ward.The change in wettability is related to the height of the micro-structure of super-hydrophobic surfaces,and the droplet will be in the Cassie state only when a certain height is reached.Maintaining the Cassie state requires a suitable surface microstructure.The Cassie state can easily transition to the Wenzel state,but tran-sitioning from the Wenzel state to the Cassie state is more difficult,and it is necessary to overcome the en-ergy barrier under the action of external forces.The morphology and size of super-hydrophobic surface micro-structure are important factors affecting the drag reduction performance,so the micro-structure param-eters can be optimized to improve the drag reduction rate of the super-hydrophobic surfaces.Through the study of wall slip and turbulent coherent structure,although the drag reduction mechanism of super-hydrophobic surfaces has achieved certain results,it still needs to be further explored.The preparation method of super-hydrophobic surfaces is cumbersome and expensive,and the use of inexpensive materials and simple preparation processes to manufacture stable super-hydrophobic surfaces has become a hot re-search topic in the future.关键词
