摘要
电极驱动的微槽道流动是微流动驱动装置中重要的应用,本文通过基于PoisonNernst-Planck-Navier-Stokes模型对电极驱动的微槽道流动进行数值模拟。通过高精度的谱方法,在流向上使用Fourier级数的Garlerkin方法,法向上使用Chebyshev多项式的Tau方法,对二维微槽道流动进行直接数值模拟,得到了基于PNPNS模型的算法在低电压和高电压边界条件情况下的结果。
The electrode-driven microchannel flow is an important application in micropump devices. This paper numerically simulates the microchannel flow driven by electrodes based on the Poison-Nernst-Planck-Navier-Stokes model. Through a high-precision spectral method, the Garlerkin method of the Fourier series is used in the flow direction, and the Tau method of the Chebyshev polynomial is used in normal direction, to perform direct numerical simulation of the two-dimensional microchannel flow, the result based on the PNPNS model at low voltage and high voltage boundary condition is obtained.
