Abstract

In this study, a micromixer with Koch fractal under electric field effect is simulated, and we studied the effects of different fractal parameters on the mixing process. These parameters include the number of fractals, the spacing of fractals, the geometric dimensions of fractals and the flow analysis of the fluid in the microchannels. Simulation displays that increasing the number of electrode pairs and increasing the fractal size are both beneficial to fluid mixing, and the optimal fractal spacing is 0.75 mm. The results show that the Koch fractal structure and the electric field effect can not only improve the flow state of the fluid effectively, but also increase the mixing index of the fluid.
