Numerical Analysis of Micro-Mixing in Rough Microchannels

Abstract:

Understanding the micro-mixing of electroosmotic flow is of both fundamental and practical significance for the design and optimization of various microfluidic devices to control fluid motion. In this paper, the governing equations of the micro-mixing in rough microchannels with rectangle surface roughness are solved using the finite element method and the effects of roughness height and space on mixing efficiency are investigated. The results indicate that the effects cannot be ignored and the mixing efficiency increases with the roughness element height and density.
