Abstract:Flexible polymeric microtubes with rectangular‐lumen are useful in chemical and bioengineering. However, improving the aspect ratio of the rectangular lumen is still a tough task. In this study, numerical simulations are carried out to study the influences of the processing parameters and the design of the extrusion die on the aspect ratio of the rectangular microchannels. Increasing the length of the inner die and reducing its width are critical to improving the aspect ratio of channels. The pressure differen… 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.
