Abstract

In this work, the combined impacts of electroosmosis and peristaltic processes are investigated to better understand the behavior of fluid flow in a symmetric channel. The Poisson–Boltzmann equation is included into the Navier–Stokes equations to account for the electrokinetic effects in micropolar fluid model. The fluid motion caused by electric fields is effectively described by incorporating electrokinetic variables in these equations. Under the premise of a low Reynolds number and small amplitude, the linearized equations are resolved. Partial differential equations are solved to yield analytical formulations for the velocity and pressure fields. As opposed to earlier research, our analysis explores the combined impacts of electroosmosis and peristaltic motion in symmetric channels. By considering these mechanisms together, we gain a comprehensive understanding of fluid movement and manipulation in microchannels. According to research on modifying the properties of fluid flow, zeta potential, applied voltage, and channel shape all affect the velocity of electroosmotic flow. In addition, the flow rate is impacted by the peristaltic motion-induced periodic pressure changes. In addition, the combined effects of peristalsis and electroosmosis show promise for accurate and efficient regulation of fluid flow in microchannels. The study reveals that the micropolar parameter modifications (0–100) have little effect whereas adjusting the coupling parameter (0–1) modifies electroosmotic peristaltic flow. Center streamlines are trapped and then aligned in a length-dependent way by the interaction of electric fields. Several microfluidic applications, including mixing, pumping, and particle manipulation, are affected by the findings of this research. The electroosmosis and peristaltic processes may be understood and used to create sophisticated microfluidic devices and lab-on-a-chip systems. This development has the potential to greatly improve performance and functionality in industries like chemical analysis, biomedical engineering, and other areas needing precise fluid control at the microscale.

对称通道流中的电渗和蠕动机制
在这项工作中,研究了电渗和蠕动过程的综合影响,以更好地理解对称通道中的流体流动行为。在纳维-斯托克斯方程中加入了泊松-波尔兹曼方程,以考虑微极性流体模型中的电动效应。通过在这些方程中加入电动变量,可以有效地描述电场引起的流体运动。在低雷诺数和小振幅的前提下,线性化方程得到了解决。通过求解偏微分方程,可以得到速度场和压力场的解析公式。与之前的研究不同,我们的分析探讨了对称通道中电渗透和蠕动运动的综合影响。通过综合考虑这些机制,我们对微通道中的流体运动和操控有了全面的了解。根据有关改变流体流动特性的研究,zeta 电位、外加电压和通道形状都会影响电渗流动的速度。此外,蠕动引起的周期性压力变化也会影响流速。此外,蠕动和电渗的综合效应为精确、高效地调节微通道中的流体流动带来了希望。研究发现,微极性参数(0-100)的调整几乎没有影响,而耦合参数(0-1)的调整却能改变电渗蠕动流。在电场的相互作用下,中心流线被截留,然后以长度相关的方式排列。这项研究成果影响了多种微流体应用,包括混合、泵送和粒子操纵。电渗和蠕动过程可被理解并用于创建复杂的微流体设备和片上实验室系统。这一发展有可能大大提高化学分析、生物医学工程等行业的性能和功能,以及其他需要在微尺度上精确控制流体的领域的性能和功能。

期刊介绍: Microfluidics and Nanofluidics is an international peer-reviewed journal that aims to publish papers in all aspects of microfluidics, nanofluidics and lab-on-a-chip science and technology. The objectives of the journal are to (1) provide an overview of the current state of the research and development in microfluidics, nanofluidics and lab-on-a-chip devices, (2) improve the fundamental understanding of microfluidic and nanofluidic phenomena, and (3) discuss applications of microfluidics, nanofluidics and lab-on-a-chip devices. Topics covered in this journal include: 1.000 Fundamental principles of micro- and nanoscale phenomena like, flow, mass transport and reactions 3.000 Theoretical models and numerical simulation with experimental and/or analytical proof 4.000 Novel measurement & characterization technologies 5.000 Devices (actuators and sensors) 6.000 New unit-operations for dedicated microfluidic platforms 7.000 Lab-on-a-Chip applications 8.000 Microfabrication technologies and materials Please note, Microfluidics and Nanofluidics does not publish manuscripts studying pure microscale heat transfer since there are many journals that cover this field of research (Journal of Heat Transfer, Journal of Heat and Mass Transfer, Journal of Heat and Fluid Flow, etc.).
