Design and Analysis of a Laminar Diffusion-Based Micromixer with Microfluidic Chip

This study aims to perform optimizatione achieve the best diffusion control between channels by designing and analysing a microfluidic-based micromixer. The design analysis of micromixer were made with COMSOL Multiphysics program. Some input output parameters must be defined for Among these parameters, inputs are coefficient inlet flow rate, while outputs velocity, pressure, concentration. Each parameter in microfluidic chip affects system. To make most optimum way, data obtained making much analysis. from this program was also provided Fuzzy Logic method optimize chip. value (5E-11 m2/s) should given channels, if rate (15E-15 m3/s) is system, velocity 0.09 mm/s. pressure 2 Pa, concentration 0.45 mol/m3. These values without damaging liquid’s supplied micromixer’s inlet.
