This research work interprets the influences of magnetic dipole over a radiative Eyring–Powell fluid flow past a stretching sheet while considering the impacts of viscous and ohmic dissipation that produce a quite illustrious effect due to the generated magnetic dipole. This whole analysis is characterized by the effects of steady, laminar, and incompressible flow. The highly nonlinear and coupled partial differential equations (PDEs) are remodeled into a system of nonlinear ordinary differential equations (ODEs) by utilizing reliable and nondimensional parameters leading to the momentum, thermal, and concentration equations, that are computationally solved using on MATLAB, and “dsolve” command on MAPLE software, in the companionship of boundary conditions. The physical constraints such as viscous and ohmic dissipation and many other sundry parametric effects are sketched with their ultimate effects on fluid flow. For the sustenance of this research with the prior work and in collaboration with the below mentioned literature review, a comprehensive differentiation is given, which defines the sustainability of the current work. The Buongiorno nanoliquid model elaborates the thermophoresis and Brownian features that are deliberately scrutinized within the influence of activation energy. Also, the skin friction coefficient, Nusselt number, and Sherwood number are illustrated in tables. The skin friction coefficient decreases with a rise in the ferromagnetic interaction parameter as well as the Hartmann number, whereas the Nusselt number and Sherwood number show variation for varying parameters. It can be observed that Eyring–Powell fluid intensifies the rate of heat and mass transfer.

考虑粘性和欧姆耗散效应的非线性辐射 Eyring-Powell 纳米流体上磁偶极子的数值模拟

这项研究工作解释了磁偶极子对通过拉伸片的辐射性 Eyring-Powell 流体流动的影响,同时考虑了粘性和欧姆耗散的影响,这些影响由于产生的磁偶极子而产生了非常显着的效果。整个分析的特点是稳定、层流和不可压缩流的影响。高度非线性和耦合的偏微分方程 (PDE) 通过利用导致动量、热和浓度方程的可靠和无量纲参数被重新建模为非线性常微分方程 (ODE) 系统,这些方程使用以下方法进行计算求解在 MATLAB 上,和 MAPLE 软件上的“dsolve”命令,在边界条件的陪伴下。诸如粘性和欧姆耗散以及许多其他杂项参数效应等物理约束都被描绘为它们对流体流动的最终影响。为了支持这项研究与先前的工作以及与下面提到的文献综述的合作,给出了一个全面的区分,它定义了当前工作的可持续性。Buongiorno 纳米液体模型详细阐述了热泳和布朗特征,这些特征在活化能的影响下进行了仔细检查。此外,表中示出了皮肤摩擦系数、努塞尔数和舍伍德数。皮肤摩擦系数随着铁磁相互作用参数和哈特曼数的增加而降低,而努塞尔数和舍伍德数显示出不同参数的变化。可以观察到,Eyring-Powell 流体增强了传热和传质速率。
