Abstract

: Nanofluids show greater heat transfer rate and characteristics of mechanical friction diminution using nano-sized hard elements to fluid. Moreover, regarding the working of heat transfer fluid, nanofluid is widely used in areas of refrigeration, shipping, automobile, chemical industry, energy, electronics, air conditioning, computer, and many other areas to cope heat transference issues. The aforesaid utilizations motivated us to encounter entropy generation aspects for Sutterby nanofluid flow configured by permeable surface. Moreover, well-known Buongiorno's model capturing same attributes of Brownian and thermophoretic-diffusions is presented for modeling and investigation. Additionally, (MHD) as well as thermal radiation effects are the part of current work. Here, we have also considered the viscous dissipation aspects. Similarity variable are used to decrease set of nonlinear PDEs into set of ODEs then resolved numerically by using bvp4c algorithm, besides the pertinent parameters are addressed graphically. The physical aspect of fluid flow, temperature, concentration for variation of involved parameters is explained with the help of graphs.

考虑辐射因素的萨特比纳米流体化学反应流的熵产分析

纳米流体表现出更高的传热率和使用纳米尺寸的硬元素来减小机械摩擦的特征。此外，在传热流体的工作方面，纳米流体被广泛应用于制冷、船舶、汽车、化工、能源、电子、空调、计算机等诸多领域，以解决传热问题。上述应用促使我们在可渗透表面配置的萨特比纳米流体流动中遇到熵生成方面的问题。此外，还提出了著名的Buongiorno模型，该模型捕获了布朗扩散和热泳扩散的相同属性，用于建模和研究。此外，(MHD)和热辐射效应是当前工作的一部分。在这里，我们还考虑了粘性耗散方面。利用相似变量将非线性偏微分方程分解为一组偏微分方程，然后用bvp4c算法进行数值解析，并对相关参数进行了图形化处理。借助图形解释了流体流动、温度、浓度随相关参数变化的物理方面。
