摘要：

We built the quasicrystal structures which are five-fold,eight-fold,ten-fold and twelve-fold rotational symmetric artificially, and 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 200-2000 s(-1). The drag-reduction can be much greater when the structure is compounded with rough surface consisting of micro/nano-structures.
