| Summary: | Miniaturization is the trend in analytical chemistry and life science. It has been
emerging into the research field of microfluidics in the application of LOC. The
application is used for biochemistry analysis and require a rapid mixing in small area.
Due to laminar flow (Reynold Number < 1) passive micromixer is the best method in
fluids mixing. Passive micromixer also depend on the channel geometry for mixing
effectiveness. In this study, four different micromixers were evaluated based on the
baseline control Y-micromixer. The micromixers are internal rib micromixer, patterned
grooves micromixer, obstruction micromixer and slanted rib micromixer. These
micromixer has 1000μm channel length, 150μm inlet length, 90o between inlets ports,
width and depth are 40μm each. The fluids used for mixing were blood which has 1.0 ×
10-6 kg/μms of viscosity and toluene which has low viscosity than blood (0.664 × 10-9
kg/μms). The fluids used to evaluate the differences in term of their visual performance
based image’s standard deviation by plotting the graph and mixing efficiency by
calculation. Based on these evaluations, the slanted rib micromixer is the best
micromixer design with the highest mixing efficiency of 99.85% at the outlet of the
channel. |
