Abstract
This paper focuses on improving mixing efficiency through the design and investigation of a micromixer that utilizes a micro-T sinusoidal geometry with a microelectrode cavity, employing numerical simulation. This work entails analyzing active mixers to enhance mixing efficiency by investigating the effects of microelectrode capacity, the placement of electrode pairs, the number of electrode pairs, and variations in voltage. The findings from the examinations indicate that the exceptional mixing efficiency of 85.7% is achieved through the utilization of the micro-T sinusoidal structure featuring a microelectrode cavity. Integrating the microelectrode cavity into the liquid structure significantly enhanced mixing by making the liquid in the microchannel charged and disturbing the contact surface. The use of numerous microelectrode cavities in the microchannel enhanced the performance of the micromixer, resulting in a reduction in mixing time. Furthermore, the research thoroughly investigated the quantity in the microchannel, uncovering that an optimal increase in a certain parameter enhances mixing efficiency. This proposal introduces a structure that holds promise for enhancing the mixing quality of the micro-T sinusoidal structure. Moreover, this study signifies remarkable progress, delivering enhanced efficiency at lowered costs for future applications.
