The Design of Microfluidic Mixer Based on Flattening for Blood Mixing Application

Abstract

The application of microchip technology has the potential to detect early health aspects. The mixing process in the medical laboratory examination with a blood check is important to determine the overall health condition and provide information on the disease suffered and also determine the treatment carried out or the next stage. This paper aims to study the simulation of microfluidic mixer devices based on flattening channels for blood mixing applications. The finite element analysis is used to study the effect of flattening channel geometry related to the microfluidic mixer performance. The results show that the mixing index above 0.98 is obtained which means the fluid was mixed homogenously. As a consequence, rapid and efficient mixing remains a challenging task within the design and development of micromixers. Furthermore, from the Reynolds number variations, it revealed that the mixing index increase when the Reynolds number increase.
