Abstract

In this article, the shape effects of copper‐water nanofluid on magnetohydrodynamic boundary layer flow and heat transfer over a nonlinear stretching sheet in a porous medium under the influence of radiation, a heat source, and Joule heating effects are studied. The primary objective of this study is to determine which shape of nanoparticle is most effective in terms of heat transfer rate and to analyze how nanoparticle shape affects it. The governing PDEs are transformed to ODEs through similarity variables, and the numerical solutions are computed with the help of MATLAB's built‐in bvp4c solver. Plots of the velocity and temperature profiles are shown for various key parameters. The stretching parameter decreases both velocity and temperature, whereas the magnetic parameter, porosity, Eckert number, radiation, and heat source escalate temperature profiles. The heat transfer rate of lamina‐shaped nanoparticles is higher than that of other shapes.
在热源、热辐射和焦耳加热条件下,纳米颗粒形状对Cu - water纳米流体在多孔介质中非线性拉伸片上磁流的影响
在本文中,研究了在辐射、热源和焦耳热效应的影响下,铜-水纳米流体的形状对多孔介质中非线性拉伸片的磁流体动力学边界层流动和传热的影响。本研究的主要目的是确定哪种形状的纳米颗粒在传热率方面最有效,并分析纳米颗粒形状如何影响传热率。通过相似变量将控制偏微分方程转换为偏微分方程,并利用MATLAB内置的bvp4c求解器计算数值解。给出了各关键参数的速度和温度分布图。拉伸参数降低了速度和温度,而磁性参数、孔隙度、Eckert数、辐射和热源使温度曲线升高。片状纳米颗粒的传热速率高于其他形状的纳米颗粒。
