Abstract

Optimization in improvement of mixing fluid in microchannel is reported in this paper. Number of articles have been reviewed regarding the mixing process of two miscible fluids. Mixing efficiency depends on the Reynolds number, velocities of the mixing fluids as well as the position and shape of the obstacles present in the microchannel. In order to have better mixing quality, various types of microfluidic devices need to be integrated with microfluidic systems. Due to low Reynolds number, the fluid diffusivity is low and hence it is required to create chaotic advection in microchannel to improve the fluid mixing efficiency by using advanced technology which is reviewed in this paper.
