KÁRMÁN VORTEX CITY OF DNA STRANDS
(2021) 25th International Conference on Miniaturized Systems for Chemistry and Life Sciences, MicroTAS 2021 p.13-14- Abstract
Kármán vortex streets are repeating patterns of swirling vortices, appearing when a fluid passes an obstacle at Re>50. We present an array of interacting vortices, a Kármán vortex city, that arises when a DNA solution flows through an array of micro posts at Re <0.5. Above thresholds in concentration and flow rate, the vortices formed behind posts interact, leading to concentration fluctuation waves. We explore the effect of lattice structure, polymer length and salt and relate the wave formation to the overlap concentration. Our work will allow us to optimize high-concentration DNA manipulation and sorting of DNA in microfluidic arrays.
