Abstract

The main objective of this work is to present a comprehensive study that scrutinize the influence of DD convection and induced magnetic field on peristaltic pumping of Boron Nitride-Ethylene Glycol nanofluid flow through a vertical complex irregular microchannel. Experimental study showed that the nanofluid created by suspending Boron Nitride particles in a combination of Ethylene Glycol exhibited non-Newtonian characteristics. Further, the Carreau's fluid model provides accurate predictions about the rheological properties of BN-EG nanofluid. In order to imitate complicated peristaltic wave propagation conditions, sophisticated waveforms are forced at the walls. The essential properties of Brownian motion and thermophoresis phenomena are also included in simulating of heat equation as well as viscous dissipation. Mathematical simulation is performed by utilizing the lubrication approach. The resulting nonlinear coupled differential equation system is solved numerically using the built-in command (ND Solve function) in the Mathematica program. Numerical and pictorial evidence is used to illustrate the importance of various physiological features of flow quantities. The major findings demonstrated that the thermal resistance is observed to rise as the Soret and Dufour numbers increase, while the dissolvent concentration and nanoparticles volume fraction have the opposite effect.

摘要

这项工作的主要目的是进行一项全面的研究,仔细研究 DD 对流和感应磁场对氮化硼-乙二醇纳米流体通过垂直复杂非规则微通道蠕动泵送的影响。实验研究表明,通过将氮化硼颗粒悬浮在乙二醇的混合物中形成的纳米流体表现出非牛顿特性。此外,Carreau 流体模型对 BN-EG 纳米流体的流变性质提供了准确的预测。为了模拟复杂的蠕动波传播条件,在壁面施加复杂的波形。布朗运动和热泳现象的基本性质也包括在模拟热方程以及粘性耗散中。通过利用润滑方法进行数学模拟。使用 Mathematica 程序中的内置命令 (ND Solve 函数) 对得到的非线性耦合微分方程组进行数值求解。数值和图像证据用于说明流动量的各种生理特性的重要性。主要发现表明,随着 Soret 和 Dufour 数的增加,热阻观察到增加,而溶剂浓度和纳米颗粒体积分数则有相反的效果。
