摘要

这项研究旨在利用数学建模来研究线性粗糙薄片上的耗散卡松纳米流体流动中的热量和质量传输力学。这项研究考虑了各种因素,如热辐射、磁场、热量产生、多孔介质的不同特性以及热泳影响。此外,它还研究了粘度、扩散率和热导率的变化,以及粘滞内摩擦和流体温度变化产生的能量耗散。该方法包括提出边界层方程,并将其转换为一组使用无尺寸变量的关联非线性常微分方程。这些方程求解策略的基础是赫尔墨特配位法(HCM),该方法以其精确性和适应性而闻名。它为复杂微分方程的求解提供了一种有条理的方法,允许精确的数值求解。图形表示法的使用确保了彻底的数据分析和清晰度,同时还提供了有关计算结果的深刻信息。代码验证方法采用与最新研究进行数值比较的方式,以确认算法的准确性和可靠性,以及与现有文献相比的适应性。研究得出的重要结论表明,热边界层和纳米流体速度随着孔隙度参数、滑移参数和磁场参数的增加而降低。

Utilizing numerical techniques for modeling radiating Casson nanofluid flow with thermophoretic phenomenon on a heated stretching surface
This work aims to use mathematical modeling to investigate the mechanics of heat and mass transport in dissipative Casson nanofluid flows over a linear rough sheet. This study considers various elements such as thermal radiation, magnetic fields, heat generation, the varied properties of porous media, and the thermophoretic impact. Besides that, it looks into the variations in viscosity, diffusivity, and thermal conductivity, as well as the energy dissipation from viscous internal friction and fluid temperature modifications. The method involves coming up with and changing the boundary layer equations into a group of linked nonlinear ordinary differential equations that use variables that do not have any dimensions. The foundation of the solution strategy for these equations is the Hermite collocation method (HCM), which is renowned for its precision and adaptability. It offers an organized approach to solving the complex differential equations, allowing for accurate numerical solutions. The use of graphical representations ensures thorough data analysis and clarity, while also providing insightful information about the computed outcomes. The code validation method uses numerical comparisons with recent research to confirm the algorithm’s accuracy and dependability, as well as its resilience in comparison to the existing literature. Important conclusions from the study show that thermal boundary layers and nanofluid velocity decrease with increases in the porosity parameter, slip parameter, and magnetic field parameter.

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.
