چکیده :

This study presents a numerical investigation of an electroosmotic micromixer equipped with sinusoidal chamber geometry to enhance fluid mixing performance. The effects of applied AC electric field frequency on concentration distribution at the outlet and final mixing quality (MQ) were analyzed. Concentration profiles along the outlet length show that lower frequencies generally lead to a steeper concentration gradient and improved mixing uniformity. Time evolution of MQ indicates that optimal frequencies can significantly enhance mixing efficiency. Results demonstrate that tuning the AC frequency is a key parameter for achieving superior mixing in electroosmotic micromixers with complex chamber designs
