摘要

近几十年来,非牛顿流体的研究吸引了众多研究人员的兴趣。非牛顿流体在包括工业应用在内的各个领域的重要意义鼓励了对它们的研究。此外,各种科学和工程过程,包括空调、作物损害、制冷、设备动力收集器和热交换器,也大大增加了传热和传质的重要性。这项工作的主要目标是使用数学方法表示拉伸片状环境上的化学反应卡逊-麦克斯韦流体。阿伦尼乌斯活化能和磁场也有一定的作用。此外,还考虑了粘性耗散、焦耳加热和非线性热辐射的后果。该方法将流体系统中的偏微分方程转换为具有适当相似度的非线性微分方程系统,随后利用 Lobatto IIIA 技术强大的计算能力进行解析。值得注意的是,速度曲线会随着麦克斯韦流体参数的增加而下降。此外,温度比参数的增加会提高流体的温度和边界层的相应厚度。

Importance of Activation Energy on Magnetized Dissipative Casson-Maxwell Fluid through Porous Medium Incorporating Chemical Reaction, Joule Heating, and Soret Effects: Numerical Study
In recent decades, the study of non-Newtonian fluids has attracted the interest of numerous researchers. Their study is encouraged by the significance of these fluids in fields including industrial implementations. Furthermore, the importance of heat and mass transfer is greatly increased by a variety of scientific and engineering processes, including air conditioning, crop damage, refrigeration, equipment power collectors, and heat exchangers. The key objective of this work is to use the mathematical representation of a chemically reactive Casson-Maxwell fluid over a stretched sheet circumstance. Arrhenius activation energy and aspects of the magnetic field also have a role. In addition, the consequences of both viscous dissipation, Joule heating, and nonlinear thermal radiation are considered. The method transforms partial differential equations originating in fluidic systems into nonlinear differential equation systems with the proper degree of similarity which is subsequently resolved utilizing the Lobatto IIIA technique’s powerful computing capabilities. It is important to recall that the velocity profile drops as the Maxwell fluid parameter increases. Additionally, the increase in the temperature ratio parameter raises both the fluid’s temperature and the corresponding thickness of the boundary layer.
