Numerical Analysis of Micro-Mixing in Rough Microchannels
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.
