Hibiscus Mucilage for Enhancing the Flow in Blood-Stream-Like Microchannel System

Active drag reduction (DR) methods have been used to enhance flow in pipelines. Such techniques could be applied in the vasculature to improve blood flow without altering the properties of the blood. However, most tested DR additives have been artificial and are considered toxic. In the present work...
