AB - The super-efficient sample mixing induced by the induced-charge  electrokinetic flow around conducting/Janus cylinder was numerically studied  in a confined |U-shaped microchannel with suddenly applied DC weak electric  filed. It’s found that there are four large circulations around the  conducting cylinder and two smaller circulations around the Janus cylinder.  The results show that samples can still be well mixed with high flux due to  the induced electroosmosis. It is demonstrated that the local flow  circulations provide effective means to enhance the flow mixing between  different solutions. The dependence of the degree of mixing enhancement on  the electric field is also predicted.
