Abstract:Low flow drag is of great importance to a variety of engineering applications, and an effective way to achieve low drag is to use bioinspired micro-structured surfaces. This work aims to reduce the skin-friction drag in closed channel flow using textured surfaces inspired by leaves of indocalamus and rice. The channel formed by a polydimethylsiloxane chunk and a silicon wafer was fabricated to study drag reduction behavior for water or liquid paraffin oil in laminar flow. Bioinspired textures were processed on… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
