Co-flowing liquids can stabilize chaotic 'whipping' in microfluidic jets
Atlanta GA (SPX) Sep 09, 2014 - Industrial wet spinning processes produce fibers from polymers and other materials by using tiny needles to eject continuous jets of liquid precursors. The electrically charged liquids ejected from the needles normally exhibit a chaotic "whipping" structure as they enter a secondary liquid that surrounds the microscopic jets. But the liquid jets sometimes form a helical wave. And that was ... more
