Abstract

Single-walled carbon nanotubes (SWNTs) and multi-walled nanotubes (MWNTs) are gaining appeal in mechanical engineering and industrial applications due to their direct influence on enhancing the thermal conductivity of base fluids. With such intriguing properties of carbon nanotubes in mind, our goal in this work is to investigate radiation effects on the flow of carbon nanotube suspended nanofluids in the presence of a magnetic field past a stretched sheet impacted by slip state. CNTs flow and heat transmission are frequently modelled in practice using nonlinear differential equation systems. This system has been precisely solved, and an accurate analytical expression for the fluid velocity in terms of an exponential function has been derived, while the temperature distribution is stated in terms of a confluent hypergeometric function. The impact of the radiation parameter, slip parameter, sloid volume fraction, magnetic parameter, Eckart and Prandtl numbers on the velocity, temperature, and heat transfer rate profiles are demonstrated using a parametric analysis. When compared to the two types of nanoparticles (Cooper and Silver) in earlier published articles, temperature profiles for single-walled nanotubes (SWNTs) and multi-walled nanotubes (MWNTs) are revealed to be particularly sensitive to radiation, solid volume fraction, and slip parameters. Nanomechanical gears, nanosensors, nanocomposite materials, resonators, and thermal materials are only a few of the present problem's technical applications.

能量收集的碳纳米管嵌入边界层理论

单壁碳纳米管(SWNTs)和多壁碳纳米管(MWNTs)由于其对提高基础流体导热性的直接影响而在机械工程和工业应用中越来越受欢迎。考虑到碳纳米管的这些有趣特性，我们在这项工作中的目标是研究辐射对碳纳米管悬浮纳米流体在磁场存在下流过受滑移状态影响的拉伸片的流动的影响。在实践中，碳纳米管的流动和传热经常使用非线性微分方程系统进行建模。对该系统进行了精确求解，导出了流体速度用指数函数表示的精确解析表达式，而温度分布用合流超几何函数表示。利用参数分析论证了辐射参数、滑移参数、固体体积分数、磁性参数、Eckart数和Prandtl数对速度、温度和传热率分布的影响。与先前发表的两种类型的纳米颗粒(Cooper和Silver)相比，单壁纳米管(SWNTs)和多壁纳米管(MWNTs)的温度曲线对辐射、固体体积分数和滑移参数特别敏感。纳米机械齿轮、纳米传感器、纳米复合材料、谐振器和热材料只是目前问题的技术应用中的一小部分。
