Design and development of oblique groove micromixer for laminar blood reagent mixing

Mixing of two fluid is an essential process for most of microfluidic device such as Lab-On-Chip (LOC) device. Mixing performance in this microsystem mainly relies on effective and rapid mixing of sample and reagent. Therefore, the development of oblique groove micromixer for application of blood and reagent mixing has been carried out. In this study, two types of fluids are involve in the mixing, which are the blood and reagent. Two mixer namely Y-Shape mixer and Y-Shape oblique groove mixer are designed and simulated using CoventorWare2010 software at low Reynolds number. The development of oblique groove micromixer are obtained by analyzing the geometries effect of groove pattern on mixing performance. In this study, it has been demonstrated that the Y-Shape mixer with the oblique groove structure located at the floor of the mixing channel can increase the mixing performance. Thus, the simulation result in this study shows that mixing performance can be enhanced when depth and width of oblique groove having 40% of the channel width with the angle of oblique groove is 45°.
