Abstract

This study presents a novel analysis of peristaltic flow involving a couple stress fluid embedded with a ternary hybrid nanofluid consisting of titanium dioxide (

T i O_{2}

), alumina (

A l_{2} O_{3}

), and copper (

C u

) nanoparticles, with blood as the base fluid, in the presence of a magnetohydrodynamics. The investigation focuses on the combined influence of entropy generation, homogeneous-heterogeneous chemical reactions, thermal radiation, viscous dissipation, thermophoresis, Brownian motion and Joule heating. The governing equations of the system are transformed into dimensionless form and solved numerically using the NDSolve in Mathematica, based a fourth-order Runge-Kutta method for accurate and efficient results. Key findings reveal that entropy generation is significantly reduced—by up to 12 % with an increase in the Hartmann number (M) and dimensionless temperature difference (

Ω

). Additionally, the inclusion of thermophoresis (Nt) and Brownian motion (Nb) enhances heat transfer, leading to a 15 % increase in temperature profile compared to traditional nanofluid models. The concentration profile demonstrates a unique dependency, showing a 10 % improvement with higher heterogeneous reaction rates (H) and Schmidt number (Sc), while the velocity profile decreases by 15 % with elevated M, indicating precise control of flow behavior in MHD environments. Furthermore, the size of the trapped bolus decreases with increasing M, offering potential for enhanced biomedical applications, such as targeted drug delivery and controlled blood flow. This study is the first to explore the combined effects of ternary hybrid nanoparticles, couple stress fluids and MHD field on peristaltic motion with entropy generation. The findings provide new insights into optimizing thermal and fluid transport processes for advanced biomedical devices and industrial heat transfer systems. Specifically, the research supports the development of advanced peristaltic pump systems for drug delivery, waste removal and fluid transport in biophysiological environments.

本研究提出了一种新颖的蠕动流分析方法，涉及在磁流体力学作用下，嵌入由二氧化钛（TiO2）、氧化铝（Al2O3）和铜（Cu）纳米颗粒组成的三元混合纳米流体的耦合应力流体的蠕动流。研究重点是熵生成、均相-异相化学反应、热辐射、粘性耗散、热泳、布朗运动和焦耳加热的综合影响。该系统的支配方程被转换为无量纲形式，并使用 Mathematica 中的 NDSolve 进行数值求解，该方法基于四阶 Runge-Kutta 方法，结果准确高效。主要研究结果表明，随着哈特曼数（M）和无量纲温差（Ω）的增大，熵的产生显著减少，最多可减少 12%。此外，热泳（Nt）和布朗运动（Nb）的加入增强了热传导，与传统纳米流体模型相比，温度曲线增加了 15%。浓度曲线表现出独特的依赖性，随着异质反应速率（H）和施密特数（Sc）的提高，浓度曲线提高了 10%，而速度曲线随着 M 的升高降低了 15%，这表明对 MHD 环境中的流动行为进行了精确控制。此外，随着 M 值的增大，被截留的栓子的尺寸也会减小，这为增强生物医学应用（如靶向给药和可控血流）提供了潜力。这项研究首次探索了三元混合纳米粒子、耦合应力流体和 MHD 场对蠕动运动和熵生成的综合影响。研究结果为优化先进生物医学设备和工业传热系统的热和流体传输过程提供了新的见解。具体来说，这项研究有助于开发先进的蠕动泵系统，用于生物生理环境中的药物输送、废物清除和流体传输。

期刊介绍： Case Studies in Thermal Engineering provides a forum for the rapid publication of short, structured Case Studies in Thermal Engineering and related Short Communications. It provides an essential compendium of case studies for researchers and practitioners in the field of thermal engineering and others who are interested in aspects of thermal engineering cases that could affect other engineering processes. The journal not only publishes new and novel case studies, but also provides a forum for the publication of high quality descriptions of classic thermal engineering problems. The scope of the journal includes case studies of thermal engineering problems in components, devices and systems using existing experimental and numerical techniques in the areas of mechanical, aerospace, chemical, medical, thermal management for electronics, heat exchangers, regeneration, solar thermal energy, thermal storage, building energy conservation, and power generation. Case studies of thermal problems in other areas will also be considered.
