Organic Additives for the Enhancement of Laminar Flow in a Brain‐Vessels‐Like Microchannel Assembly

Flow enhancement which traditionally applicable in reducing the pressure drop in the core of the turbulent flow in pipes, ducts and conduits has extended its impact into medical field. A minute amount of flexible long chain polymers has been proven to be effective in enhancing and improve the blood...
