Numerical Study on Electroosmotic Flow in Trapezoidal Microchannels with Variable Length Ratio

摘要：

The analysis of electroosmotic flow mechanisms in trapezoidal microchannels with variable length ratio 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 the electrical potential profile and electroosmotic flow field. The detailed numerical results show us that the characteristics of electroosmitc flow can be influenced by the length ratio of the trapezoidal microchannels, i. e. the increase in the length ratio leads to the higher average velocity and volumetric flow rate.
