| Popis: | 100 Design, simulation and optimization of a serial lamination micromixer are adapted with the concept of vortex-producing obstacle. Although the fluid motion is three-dimensional, the channel merely requires a simple fabrication process of adhering two layers of polymer. Optimization is analyzed with two main geometric parameters of the design. Simulation through one computational fluid dynamics software is used to optimize these two variables, while taking into consideration the physical properties of the fluid, i.e., viscosity and the Reynolds number. By additional consideration of the velocity field, a new mixing index is created based on the traditional mixing index. The inherent advantage of this new mixing index is that it always produces smoother curves than that of the traditional one. Optimization results are achieved by using the regression analysis with the two geometric parameters |
