We investigated the effect of superhydrophobic walls on electrokinetics phenomena in a finite-length microchannel with superhydrophobic walls (in both transient and steady-state). We implemented the effect of superhydrophobicity using Navier’s slip-length. To include the importance of the electric double-layer, we scaled the slip-length with respect to Debye-length (κ^-1${\kappa }^{-1}$). By increasing the slip-length from 0 to 144 nm (1.5κ^-1${\kappa }^{-1}$), streaming-current, streaming-potential, flow-rate and electrokinetic energy conversion increased by 2.55, 2.44, 1.8, and 3.4 folds, accordingly. The electrokinetic energy conversion of each microchannel was in the order of picowatt. To produce more energy, an array of microchannels should be used.

我们研究了在具有超疏水壁的有限长度微通道中（瞬态和稳态）超疏水壁对电动现象的影响。我们使用Navier的滑移长度实现了超疏水性的​​效果。为了包括双电层的重要性，我们将滑移长度相对于德拜长度（κ ^-1${\kappa }^{--\mathrm{1个}}$）。通过将滑动长度从0增加到144 nm（1.5κ ^-1${\kappa }^{--\mathrm{1个}}$），流电流，流电势，流速和电动能量转换分别增加了2.55倍，2.44倍，1.8倍和3.4倍。每个微通道的动能转换约为皮瓦。为了产生更多的能量，应该使用微通道阵列。
