Abstract

In this study, an effort is made to model the thermal conduction and mass diffusion phenomena in perspective of Buongiorno’s model and Cattaneo-Christov theory for 2D flow of magnetized Burgers nanofluid due to stretching cylinder. Moreover, the impacts of Joule heating and heat source are also included to investigate the heat flow mechanism. Additionally, mass diffusion process in flow of nanofluid is examined by employing the influence of chemical reaction. Mathematical modelling of momentum, heat and mass diffusion equations is carried out in mathematical formulation section of the manuscript. Homotopy analysis method (HAM) in Wolfram Mathematica is utilized to analyze the effects of physical dimensionless constants on flow, temperature and solutal distributions of Burgers nanofluid. Graphical results are depicted and physically justified in results and discussion section. At the end of the manuscript the section of closing remarks is also included to highlight the main findings of this study. It is revealed that an escalation in thermal relaxation time constant leads to ascend the temperature curves of nanofluid. Additionally, depreciation is assessed in mass diffusion process due to escalating amount of thermophoretic force constant.
从Buongiorno模型和改进的热通量和质量通量理论看拉伸圆柱体的Burgers流体流动
本文从Buongiorno模型和cattanio - christov理论的角度,对磁化Burgers纳米流体在圆柱体拉伸作用下二维流动的热传导和质量扩散现象进行了模拟。此外,还考虑了焦耳加热和热源的影响,探讨了热流机理。此外,利用化学反应的影响,研究了纳米流体在流动中的质量扩散过程。在论文的数学公式部分对动量、热量和质量扩散方程进行了数学建模。利用Wolfram Mathematica软件中的同伦分析方法(HAM),分析了物理无量纲常数对Burgers纳米流体流动、温度和溶质分布的影响。在结果和讨论部分对图形结果进行了描述和物理证明。在手稿的最后还包括结束语部分,以突出本研究的主要发现。结果表明,随着热松弛时间常数的增大,纳米流体的温度曲线呈上升趋势。此外,在质量扩散过程中,由于热泳力常数的不断增大,估计了衰减。
