Abstract

This work investigates the problem of time- and space-dependent thin film thickness, specifically focusing on the flow of a Carreau–Yasuda (CY) ternary nanofluid over a porous stretching and rotating disk. The study examines how the thin film thickness varies under partial slip conditions. The CY-ternary nanofluid is composed of silver, alumina, and carborundum nanocombination in ethylene glycol. Also, the study takes into account the effect of thermal radiation with the extension of a magnetic field. To solve the unsteady nonlinear problem, it is transformed into a nonlinear problem and solved using the homotopy analysis method (HAM). The acquired data, together with the CY-ternary nanofluid percentage heat transfer augmentation, are shown visually and quantitatively. The results demonstrate that the CY-ternary nanofluid thin film thickness is influenced by the flow parameters. Moreover, a decrease in thin film thickness is facilitated by rotation, magnetic field, and porosity, which significantly boosts heat transfer rates. These findings are practical applications and offer opportunities for improved thermal management in engineering, biomedical, and industrial processes.

探索粘弹性潜能:旋转圆盘上的 Carreau-Yasuda 三元纳米流体的非稳态磁流体薄膜流
这项研究探讨了薄膜厚度随时间和空间变化的问题,特别关注 Carreau-Yasuda (CY) 三元纳米流体在多孔拉伸旋转盘上的流动。研究探讨了薄膜厚度在部分滑移条件下的变化情况。CY 三元纳米流体由乙二醇中的银、氧化铝和碳化硅纳米复合体组成。此外,研究还考虑了磁场延伸的热辐射效应。为了解决非稳态非线性问题,将其转化为非线性问题,并使用同调分析方法(HAM)进行求解。所获得的数据以及 CY 三元纳米流体百分比传热增强都以直观和定量的方式显示出来。结果表明,CY-三元纳米流体薄膜厚度受流动参数的影响。此外,旋转、磁场和孔隙率会促进薄膜厚度的减小,从而显著提高传热率。这些发现具有实际应用价值,为改善工程、生物医学和工业流程中的热管理提供了机会。

期刊介绍: Mechanics of Time-Dependent Materials accepts contributions dealing with the time-dependent mechanical properties of solid polymers, metals, ceramics, concrete, wood, or their composites. It is recognized that certain materials can be in the melt state as function of temperature and/or pressure. Contributions concerned with fundamental issues relating to processing and melt-to-solid transition behaviour are welcome, as are contributions addressing time-dependent failure and fracture phenomena. Manuscripts addressing environmental issues will be considered if they relate to time-dependent mechanical properties. The journal promotes the transfer of knowledge between various disciplines that deal with the properties of time-dependent solid materials but approach these from different angles. Among these disciplines are: Mechanical Engineering, Aerospace Engineering, Chemical Engineering, Rheology, Materials Science, Polymer Physics, Design, and others.
