Abstract

The current research deals with analytical analysis of Marangoni convection on ethylene glycol base hybrid nanofluid two-dimension flow with viscous dissipation through a porous medium, which have some important application in mechanical, civil, electronics, and chemical engineering. Two types of nanoparticles one is sliver and other is graphene oxide and ethylene glycol is used as base fluid in this research work. The authors applied appropriate transformations to convert a collection of dimension form of nonlinear partial differential equations to dimensionless form of nonlinear ordinary differential equations. The transformed nonlinear ordinary differential equations are solved with the help of an approximate analytical method known as the homotopy analysis method. The effects of various parameters, including nanoparticle volume fraction, porosity parameter, Marangoni convection, and Eckert number, on energy and momentum profiles are analyzed, with the results illustrated using graphs. A physical explanation is provided to simulate and evaluate the behavior of nanofluid structures, such as temperature and velocity, in response to changes in these influencing factors.

摘要

当前的研究涉及对通过多孔介质的具有粘性耗散的基于乙二醇的混合纳米流体二维流动中的马兰戈尼对流进行分析，这在机械、土木、电子和化学工程中有一些重要应用。在这项研究工作中，使用了两种类型的纳米颗粒，一种是银，另一种是氧化石墨烯，并且乙二醇用作基液。作者应用适当的变换将一组非线性偏微分方程的维数形式转换为非线性常微分方程的无量纲形式。借助一种称为同伦分析方法的近似解析方法求解变换后的非线性常微分方程。分析了包括纳米颗粒体积分数、孔隙率参数、马兰戈尼对流和埃克特数在内的各种参数对能量和动量分布的影响，结果用图表说明。提供了物理解释以模拟和评估纳米流体结构（如温度和速度）响应这些影响因素变化的行为。
