摘要

本文研究了用卡普托分数阶导数(CFD)计算非定常对流流的辐射卡森纳米流体模型的分析研究。乙二醇(EG)被用作基液,氧化石墨烯(GO)和碳纳米管(CNTs)被用作纳米颗粒。通过应用适当的无量纲变量对问题的主要偏微分方程进行了无量纲化。将傅里叶正弦变换和拉普拉斯变换相结合,得到了无量纲控制方程的解。为了对该问题进行大量的研究,借助欧拉反演,利用MATLAB软件编程,制作了图形插图和表格。我们研究了[公式:见文本],Gr, Pr,[公式:见文本],R,[公式:见文本],振荡对分数热量和动量方程的影响。利用流体的性质,取得了重要的发现,表明了许多流动参数和分数参数的一些元素。在[公式:见文本]和[公式:见文本]时,[公式:见文本]的热剖面增加[公式:见文本],[公式:见文本]的热剖面减少。[公式:见文]和[公式:见文]在[公式:见文]和1.4处,速度曲线随着R的增大而增大,而Gr的减小。不同形状的纳米颗粒被执行普通分数参数,这是增加温度和速度。

The thermal radiation effect on Casson nanofluids EG-GO and EG-CNTs models using Caputo fractional order derivative with shape effects: Via analytical investigations
This research examines the analytical investigations for radiating Casson nanofluid models with unsteady convecting flow, which are valued by the order of Caputo fractional derivative (CFD). Ethylene glycol (EG) is used as a base fluid, and graphene oxide (GO) and carbon nanotubes (CNTs) are used as nanoparticles. The problem’s leading PDEs are nondimensionalized by applying the proper nondimensional variables. The solutions to the dimensionless governing equations are found by using the Fourier sine and Laplace transformation techniques together. For an enormous study of the problem, graphical illustrations and tables are developed by using MATLAB software programming with the help of Euler inversion. We examine the impact on the fractional heat and momentum equation of the [Formula: see text], Gr, Pr, [Formula: see text], R, [Formula: see text], oscillations. Using the properties of the fluid, important discoveries were made that indicated a number of elements for a number of flow parameters as well as fractional parameters. The thermal profiles are increased for [Formula: see text] decreased for [Formula: see text] at [Formula: see text] and [Formula: see text]. The velocity profiles are increased for R and Gr decreased for [Formula: see text] and [Formula: see text] at [Formula: see text] and 1.4. Different shapes of nanoparticles are performed for ordinary fractional parameters, which are increased for temperature as well as velocity.

期刊介绍: Launched in 1987, the International Journal of Modern Physics B covers the most important aspects and the latest developments in Condensed Matter Physics, Statistical Physics, as well as Atomic, Molecular and Optical Physics. A strong emphasis is placed on topics of current interest, such as cold atoms and molecules, new topological materials and phases, and novel low dimensional materials. One unique feature of this journal is its review section which contains articles with permanent research value besides the state-of-the-art research work in the relevant subject areas.
