Popis: In order to research the characteristic of flow drag reduction on large area super-hydrophobic surface, we have been designed a new processing technology to construct a micro-nano structure super-hydrophobic surfaces which formed by surface nanometer fly ash cenosphere. The experimental result of the flow drag reduction tested on macro-scale channel in laminar flow is very well, and the maximum drag reduction is 25.6%.
