摘要

在各种工业中,一个重要的方面是冷却过程,在冷却过程中材料表现出完美的形状和尺寸。针对上述性质,本研究试图将热辐射和耗散的物质性质结合到水基混合纳米流体中。流体通过嵌入渗透性介质的拉伸圆柱体以及磁场和热辐射的影响,在动量和能量剖面中进行了描述。除此之外,Hamilton-Crosser电导率模型对不同形状的碳纳米管(CNT)纳米颗粒的行为及其体积浓度的影响也至关重要。利用适当的变换规则,将控制方程的量纲形式转化为无量纲形式。此外,所设计的模型采用传统的基于射击的龙格-库塔四阶技术进行处理。不同成分的重要性质用图形表示,与前期研究的验证显示出良好的相关性。此外,结果的重要特征是;在热浮力增加的驱动下,表面冷却提高了流体速度,同时影响了曲率参数和剖面,从而减缓了纳米颗粒的积累。

Performance of carbon nanotubes (CNTs) on the development of radiating hybrid nanofluid flow through an stretching cylinder
In various industries, one of the important aspects is the cooling processes for which the material exhibits its perfect shape and size. Intending to the aforementioned property the current investigation leads to carry out the features of the materialistic property of thermal radiation and the dissipative heat by incorporating these in the water-based hybrid nanofluid. The fluid past a stretching cylinder embedded with a permeable medium and the impact of the magnetic field, and thermal radiation are depicted in momentum and energy profiles. In addition to that, the role of the Hamilton-Crosser conductivity model for the behavior of various shapes of the carbon nanotube (CNT) nanoparticles with their volume concentration is also vital. The transformation of the dimensional form of the governing equations into the non-dimensional form is obtained with the use of proper transformation rules. Further, the proposed designed model is handled by employing the traditional shooting-based Runge-Kutta fourth-order technique. The significant properties of different components are deployed graphically and the validation with earlier study shows a good correlation. Moreover, the important characteristics of the outcomes are; the surface cooling, driven by increased thermal buoyancy, promotes fluid velocity while simultaneously influencing the curvature parameter and profile to slow down the accumulation of nanoparticles.
