Abstract

On behalf of the improvement of the liquids mixing in microchips, a new method for enhancing the mixing between two liquids was tested by using magnetic particles into one kind of liquid. The mixing process of two liquids in Y-type microchannel was observed, the mixing length under the stationary magnetic field could be decreased to 2 orders of magnitude comparing with the case of no magnetic field. The results of the numerical simulation indicate also that the mixing is enhanced obviously.
