Abstract

Carbon nanotubes (CNT) are used in a variety of applications, including energy storage, device modelling, automotive parts, water filters, thin-film electronics, coating etc. The present article investigates the steady three-dimensional (3D) magnetohydrodynamics (MHD) rotating flow of water based nanofluid containing CNT namely SWCNT and MWCNT past a stretching/shrinking sheet in occurrence of magnetic field and homogeneous-heterogeneous chemical reactions. Further, the heat transfer phenomena is analyzed in presence of thermal radiation and heat source/sink. The governing partial differential equations (PDEs) are converted to non-linear ordinary differential equations (ODEs) by using suitable similarity transformations, and then solved numerically using bvp4c code of MATLAB software. The impacts of magnetic field, rotational, suction/injection, thermal radiation, heat source/sink parameters, nanoparticle (NP) volume fraction, and homogeneous and heterogeneous reactions on the velocity, temperature, and concentration profiles as well as the skin friction coefficient and Nusselt number are presented in graphs and tables. It is found that The primary velocity decreases while the second velocity increases for higher values of rotational parameter and the flow dominates in MWCNTs the SWCNTs.

辐射纳米流体在拉伸片上的三维 MHD 旋转流与同质-异质化学反应

摘要碳纳米管（CNT）应用广泛，包括储能、设备建模、汽车零部件、水过滤器、薄膜电子、涂层等。本文研究了含有碳纳米管（即 SWCNT 和 MWCNT）的水基纳米流体在磁场和均相-异相化学反应作用下经过拉伸/收缩片时的稳定三维（3D）磁流体力学（MHD）旋转流动。此外，还分析了存在热辐射和热源/散热时的传热现象。通过适当的相似变换，将支配偏微分方程（PDE）转换为非线性常微分方程（ODE），然后使用 MATLAB 软件的 bvp4c 代码进行数值求解。磁场、旋转、吸力/喷射、热辐射、热源/散热参数、纳米粒子（NP）体积分数、同相反应和异相反应对速度、温度和浓度曲线以及表皮摩擦系数和努塞尔特数的影响以图和表的形式呈现。研究发现，当旋转参数值越高时，初级速度越低，而二级速度越高，在 MWCNTs 和 SWCNTs 中流动占主导地位。

期刊介绍： Journal of Engineering Thermophysics is an international peer reviewed journal that publishes original articles. The journal welcomes original articles on thermophysics from all countries in the English language. The journal focuses on experimental work, theory, analysis, and computational studies for better understanding of engineering and environmental aspects of thermophysics. The editorial board encourages the authors to submit papers with emphasis on new scientific aspects in experimental and visualization techniques, mathematical models of thermophysical process, energy, and environmental applications. Journal of Engineering Thermophysics covers all subject matter related to thermophysics, including heat and mass transfer, multiphase flow, conduction, radiation, combustion, thermo-gas dynamics, rarefied gas flow, environmental protection in power engineering, and many others.
