We built the quasicrystal structures which are five-foldeight-foldten-fold and twelve-fold rotational symmetric artificiallyand measured their drag-reduction in the mixed solution of water and glycerin by viscometer. We found the twelvefold symmetric structure has a drag-reduction of 15%—9% when shear rate is 200—2000s-1. The drag-reduction can be much greater when the structure is compounded with rough surface consisting of micro/nano-structures.
