摘要

摘要 研究了稳定拉伸片上混合纳米流体膜的磁流体边界层流动和热传递过程。研究了倾斜磁场、切线双曲流动和粘性耗散对动量和热边界层的影响。主导方程是应用非维变换转换成非线性普通方程的 PDEs。利用频谱松弛法对具有无滑动边界条件的非二维控制方程进行数值求解。该模拟是在 MATLAB 应用程序的配合下完成的。在极限情况下,目前的结果与文献相吻合,并且非常一致。为了分析混合纳米流体粒子的流动行为、热物理特性和传输性质,我们研究了以乙二醇为基液的各种混合纳米流体粒子,它们分别是铁-铜(Fe_{3}O_{4}\)和单壁碳纳米管-氧化铜(SWCNT{-}CuO\)。通过图表探讨了磁参数、普朗特数、布林克曼数、幂律指数、魏森伯格数和倾角等新参数的影响。

Numerical Investigation of Heat Transfer Enhancement on Tangent Hyperbolic Fluid over a Stretching Sheet with an Inclined Magnetic Field Filled with Hybrid Nanofluids

Abstract

Magnetohydrodynamic boundary layer flow and heat transmission processes with a hybrid nanofluid film over a steady stretched sheet are taken into consideration. The impressions of an angled magnetic field, tangent hyperbolic flow, and viscous dissipation upon the momentum and thermal boundary layer are investigated. The leading equations are PDEs transfigured into nonlinear, ordinary ones that apply a non-dimensional transformation. Spectral relaxation methods are exploited for numerical solutions to non-dimensional governing equations with no-slip boundary conditions. This simulation was constructed with the cooperation of the application MATLAB. Present outcomes are matched with literature in the limiting cases and are an excellent agreement. To analyze the flow behavior, thermal physical characteristics, and the nature of the hybrid nanofluid particles’ transport properties, we look at various kinds of hybrid nanofluid particles with the base fluid ethylene-glycol (\(EG\)), which are Ferro–Copper, (\(Fe_{3}O_{4}\)–Cu) and Single walled carbon nanotubes–Copper Oxide, \(SWCNT{-}CuO\). The consequences of emerging parameters such as Magnetic parameter, Prandtl number, Brinkman number, Power law index, Weissenberg number, and Angle of inclination are explored through graphs The local skin friction and Nusselt number are also graphically displayed with respect to the above parameters.

期刊介绍: Journal of Engineering Thermophysics is an international peer reviewed journal that publishes original articles. The journal welcomes original articles on thermophysics from all countries in the English language. The journal focuses on experimental work, theory, analysis, and computational studies for better understanding of engineering and environmental aspects of thermophysics. The editorial board encourages the authors to submit papers with emphasis on new scientific aspects in experimental and visualization techniques, mathematical models of thermophysical process, energy, and environmental applications. Journal of Engineering Thermophysics covers all subject matter related to thermophysics, including heat and mass transfer, multiphase flow, conduction, radiation, combustion, thermo-gas dynamics, rarefied gas flow, environmental protection in power engineering, and many others.
