Title: PLIF measurements of mixing efficiency in a microfluidic mixer Description: This newly designed micro-mixer utilizes centrifugal, Coriolis and pressure forces to achieve efficient mixing. The mixer is mounted on a rotating platform. Different fluids from two micro-chambers on the right are moved through the middle mixing chamber (containing a “fishbone”) by centrifugal force while building pressure in the lower left chamber. When rotation stops, fluid is pushed back through the fishbone chamber by pressure, completing the mixing cycle. Mixing chamber dimensions are 5 x 10 mm. At 1 min into the movie RPM is increased and at 1 min 40 sec rotation stops, allowing the pressure build up in lower left chamber to push the fluid back through the mixing chamber, completing the mixing cycle.
