The present study analyzes the comparison of the Xue and Yamada-Ota models for a hybrid nanoliquid flow in porous media occurring amidst a rotating channel with surface catalyzed reaction. Here, the hybrid nanofluid flow is studied under the effect of Cattaneo Christov (C-C) heat flux and homogenous heterogeneous (Homo-Hetero) chemical reaction with entropy generation minimization analysis. The assumptions of the viscosity of hybrid nanomaterial fluid and variable thermal conductivity are added characteristics to the inimitability of the flow model. Two kinds of nanoparticles, namely single-wall carbon nanotubes and multi-wall carbon nanotubes with ethylene glycol (EG) as the base fluid are considered. Carbon nanotubes possess diverse applications in daily life including energy storage, drug delivery, cancer treatment, tissue generation, platelet activation, magnetic force microscopy, and microwave absorption, etc. Similarity transformations are utilized to translate the modeled problem into the coupled ordinary differential equations. This system of ordinary differential equations is addressed numerically. The graphical outcomes are scrutinized by utilizing the MATLAB software bvp4c function. The results revealed that the velocity profile decreases for the higher rotation parameter while increases for the escalated slip parameter. Furthermore, the fluid concentration and temperature are on the decline for higher surface catalyzed reaction and thermal relaxation parameters respectively.
本研究分析了在旋转通道中多孔介质内发生的表面催化反应混合纳米流体流动的薛定谔和山田-太田模型的比较。在考坦诺-克里斯托夫(C-C)热通量和均相-非均相(Homo-Hetero)化学反应的影响下,研究了混合纳米流体的流动,同时进行了熵产生最小化分析。混合纳米材料流体的粘度和可变热导率的假设是对流动模型的不可模仿性的附加特征。考虑了两种纳米粒子,即单壁碳纳米管和多壁碳纳米管,以乙二醇(EG)为基液。碳纳米管在日常生活中有多种应用,包括储能、药物输送、癌症治疗、组织生成、血小板激活、磁力显微镜和微波吸收等。相似变换用于将模型问题转换为耦合常微分方程。这个常微分方程组是用数值方法解决的。使用 MATLAB 软件 bvp4c 函数对图形结果进行了详细研究。结果表明,速度剖面随旋转参数的增加而减小,随滑移参数的增加而增加。此外,对于较高的表面催化反应和热弛豫参数,流体浓度和温度分别呈下降趋势。
