Abstract

This work presents a comparison of radiative magnetohydrodynamics (MHD) Bingham and Newtonian fluids across a nonlinear stretching sheet (SS), considering thermoelectric effects, chemical processes, and Joule heating. The governing equations are converted into Ordinary Differential Equation (ODE) form using suitable non-dimensional variables and parameters as well as employed a numerical strategy that combines the Nachtsheim-Swigert (N-S) shot method with the 6th order Runge-Kutta (R-K) algorithm. Comparing the behaviors of Bingham and Newtonian fluids is the main objective, which reveals intricate linkages between different physical phenomena, chemical processes, and radiative MHD on nonlinear stretching sheets. The dynamics of concentration, primary and secondary velocities, skin friction, heat and mass transfer rates, temperature, and other dimensionless parameters are graphically presented in the research. Important results indicate that compared to Newtonian fluid flow, Bingham fluid flow decreases primary velocity by 7.01% greater. Furthermore, on a nonlinear stretching sheet, temperature increases by 38.09% higher than on a linear one. In Newtonian fluid, thermal radiation acts as an increasing factor but in Bingham fluid, it acts as a decreasing factor. At a 95% confidence level, the regression analysis shows a substantial interaction between factors influencing the Nusselt number, with correlation values (R²) of 98.11% for Bingham fluids and 98.79% for Newtonian fluids. The Nusselt number and Joule heating for Newtonian fluid have a correlation study of 90.90%, whereas for Bingham fluid it is 83.69%. The improved thermal performance linked with Bingham fluid flow is highlighted by these studies, which have potential in tissue engineering, medication delivery systems, and renewable energy.

辐射 MHD 宾汉姆流体和牛顿流体流过非线性拉伸片时的热电效应和焦耳效应数据对比分析

本研究比较了非线性拉伸片（SS）上的辐射磁流体（MHD）宾汉流体和牛顿流体，并考虑了热电效应、化学过程和焦耳加热。利用合适的非维度变量和参数将控制方程转换为常微分方程（ODE）形式，并采用了结合纳赫茨海姆-斯维格特（N-S）射出法和六阶 Runge-Kutta 算法的数值策略。主要目的是比较宾汉流体和牛顿流体的行为，揭示非线性拉伸片上不同物理现象、化学过程和辐射 MHD 之间错综复杂的联系。研究以图表形式展示了浓度、一次和二次速度、表皮摩擦、传热和传质速率、温度和其他无量纲参数的动态变化。重要结果表明，与牛顿流体流动相比，宾厄姆流体流动的一次速度降低了 7.01%。此外，在非线性拉伸片上，温度的升高比线性拉伸片高 38.09%。在牛顿流体中，热辐射是一个增加因素，但在宾汉流体中，热辐射是一个减少因素。在 95% 的置信水平下，回归分析表明影响努塞尔特数的因素之间存在实质性的相互作用，宾汉流体的相关值 (R2) 为 98.11%，牛顿流体的相关值 (R2) 为 98.79%。牛顿流体的努塞尔特数与焦耳热的相关性为 90.90%，而宾汉流体的相关性为 83.69%。这些研究强调了与宾汉流体流动相关的热性能改善，这在组织工程、药物输送系统和可再生能源方面具有潜力。

期刊介绍： Thermal Science and Engineering Progress (TSEP) publishes original, high-quality research articles that span activities ranging from fundamental scientific research and discussion of the more controversial thermodynamic theories, to developments in thermal engineering that are in many instances examples of the way scientists and engineers are addressing the challenges facing a growing population – smart cities and global warming – maximising thermodynamic efficiencies and minimising all heat losses. It is intended that these will be of current relevance and interest to industry, academia and other practitioners. It is evident that many specialised journals in thermal and, to some extent, in fluid disciplines tend to focus on topics that can be classified as fundamental in nature, or are ‘applied’ and near-market. Thermal Science and Engineering Progress will bridge the gap between these two areas, allowing authors to make an easy choice, should they or a journal editor feel that their papers are ‘out of scope’ when considering other journals. The range of topics covered by Thermal Science and Engineering Progress addresses the rapid rate of development being made in thermal transfer processes as they affect traditional fields, and important growth in the topical research areas of aerospace, thermal biological and medical systems, electronics and nano-technologies, renewable energy systems, food production (including agriculture), and the need to minimise man-made thermal impacts on climate change. Review articles on appropriate topics for TSEP are encouraged, although until TSEP is fully established, these will be limited in number. Before submitting such articles, please contact one of the Editors, or a member of the Editorial Advisory Board with an outline of your proposal and your expertise in the area of your review.
