Numerical investigation of electroosmotic mixing in a contraction–expansion microchannel
Y Gong, X Cheng - Chemical Engineering and Processing-Process …, 2023 - Elsevier
345 天前 - Electroosmotic micromixing is generally a highly desirable technique in
microanalysis systems due to its ability to mix fluids at the microliter level. Herein, a
contraction-expansion microchannel is used to conduct a numerical study on the mixing
caused by AC electroosmotic. We investigate the flow and concentration field distributions in
the microchannel and observe two circulation flows and four rotating vortices generated in
the expansion chamber by the influence of AC electric fields. The generation of the rotating …
