Numerical study on electroosmotic flow in trapezoidal microchannels

摘要：

The analysis of electroosmotic ow mechanism in trapezoidal microchannels is performed in this work. The coupled Poisson-Boltzmann equation, Laplace equation, and modified Navier-Stokes equation are solved by finite volume method to describe distribution of electroosmotic ow. The detailed numerical results show that the salt concentration and applied electrical potential have great effects on the fundamental characteristics of elelctroosmotic ow. The most important finding is that the corner and wall effects in trapezoidal microchannels are stronger than those in rectangular microchannels.
