Abstract

Nanofluids have analysis of wide applications of energy technologies in recent times as the thermal amplification of several manufacturing industries. A mathematical model is developed to stimulate electrokinetic transfer through peristaltic pumping of couple-stress micropolar nanofluids in a microchannel. The effects of Joule heating and chemical reaction have been considered. The remarkable properties of nanofluid are demonstrated by thermophoresis and Brownian motion characteristics. Thermophoresis has relevance in mass transport processes in many higher temperature gradient operating systems. The highly non-linear partial differential equations into ordinary differential equations by using appropriate similarities transformations. The graphical estimates are presented for the axial velocity, spin velocity, temperature of nano fluid, concentration and pumping characteristics. The outcomes of this study reveal the activation of Joule heating and chemical reaction effects in electroosmosis peristaltic transport of couple-stress, micropolar and nanofluids. This model is applicable to the study of chemical fraternization/separation procedures and bio microfluidics devices for the resolution of diagnosis.

耦合应力、微极性和纳米流体电渗透蠕动传输中的焦耳加热和化学反应效应分析

纳米流体分析了近年来能源技术的广泛应用，作为几个制造业的热放大。建立了一个数学模型，通过微通道中耦合应力微电极纳米流体的蠕动泵送来刺激电动传递。考虑了焦耳加热和化学反应的影响。热泳和布朗运动特性证明了纳米流体的显著性质。热电泳在许多更高温度梯度操作系统中的质量传输过程中具有相关性。通过适当的相似性变换将高度非线性的偏微分方程转化为常微分方程。给出了纳米流体的轴向速度、自旋速度、温度、浓度和泵送特性的图形估计。这项研究的结果揭示了耦合应力、微电极和纳米流体的电渗蠕动传输中焦耳加热和化学反应效应的激活。该模型适用于化学亲和/分离程序和生物微流体装置的研究，以解决诊断问题。
