摘要

微型设备的制造引发了对微流体和微机电系统的广泛科学研究。这些装置被广泛应用于各种技术领域,但有关纳米流体的微流体装置的研究却相对较少。针对这一问题,利用 Debye-Hückel 线性化和格林函数法,提供了在压力梯度和磁场耦合效应下,纳米流体通过多孔微管的电动能量转换(EKEC)效率。结果表明,方波的周期性激励能更有效地提高 EKEC 的效率。此外,与之前的研究相比,在 R = 0.2 时,平均速度与余弦波形非常一致。值得注意的是,与余弦波相比,三角波的平均速度达到 47%,方波达到 85%。

Electrokinetic energy conversion of nanofluids in porous microtubes with Green’s function
Micro-devices fabrication has led to extensive scientific research on microfluidics and microelectromechanical systems. These devices are used for a wide range of technological applications, but research on microfluidic devices for nanofluids is relatively scarce. In response to this problem, the electrokinetic energy conversion (EKEC) efficiency of nanofluids is provided under the coupling effect of pressure gradient and magnetic field through porous microtubes using the Debye–Hückel linearization and the Green’s function method. The results show that the periodic excitation of the square waveform is more effective in increasing the EKEC efficiency. In addition, compared with previous studies, the average velocity is in good agreement with the cosine waveform at R = 0.2. It is worth noting that compared to cosine waves, the average velocity reaches 47% in triangular waves and 85% in square waves.
