We designed a new type of T-type electroosmotic micromixer with variable modules (EMVMs). By applying 7V alternating current (AC) voltage to the EMVM, the mixing efficiency at different Reynolds number (Re) is discussed by changing the rotation angles of modules at different positions in different directions. We found that the mixing efficiency of the EMVM can reach 99% when the first block is rotated along the xz-axis. Then, we change the torsion angle of the same variable module and find that the mixing efficiency can reach 99.3% when the torsion is 0∘. Finally, we change the voltage value and find that the mixing efficiency of the EMVM increases with the increase of voltage values.

可变模块电渗微混合器的数值模拟

我们设计了一种新型吨具有可变模块（EMVM）的-型电渗微混合器。通过对EMVM施加7V交流（AC）电压，通过改变模块在不同方向不同位置的旋转角度来讨论不同雷诺数（Re）下的混合效率。我们发现当第一个块沿着xz-轴。然后，我们改变同一个变量模块的扭转角，发现当扭转为0∘. 最后，我们改变电压值，发现EMVM的混合效率随着电压值的增加而增加。
