Abstract
Two-fluid mixing is an essential process in many microfluidic devices for Biomedical Micro-Electro-Mechanical Systems (BioMEMS) applications. For example, various biomedical and biochemical process involve the mixing of two fluids. The performance of such processes relies on effective and rapid mixing of samples and reagents. This project discussed the mixing characteristics of two fluids with different properties in term of Reynolds number (Re) with Y-Shape glass based micromixer. Blood flow properties was used to be mixed with a particular type of reagents which the difference in the properties of these two mixing fluids will be adjusted by varying the viscosity. The laminar mixing of the two fluids inside these micromixers was simulated at low «<I) Re flow. The Reynolds number parameters consist ofvs, mean fluid velocity in m S·I, L is the characteristic length in m, f1 is the absolute dynamic fluid viscosity in kgrn-Is-I, and p is the density of the fluid in kgrn-3. Simulation and visualizations results were obtained using CoventorWare2006. The mixing characterization will be based on the visualization results of the distribution field in term of viscosity. In this study it was found that higher Reynolds number will results in better mixing and smaller mixing channel width.
