摘要

目前的分析报告了纳米流体在磁效应和卡塔尼奥-克里斯托夫热通量作用下穿过漩涡圆柱体的热量和质量传输。本研究的目的是考察混合纳米流体在热源/热沉和反应物影响下的能量和质量传输。混合纳米流体是由银(Ag)和金(Au)纳米粒子(NPs)分散在基础流体乙二醇(C2H6O2)中制备而成。流动现象以非线性偏微分方程的形式表示,并通过相似性替换转换为非维度形式。为了对问题进行计算估算,采用了参数延续法。速度、质量和能量轮廓与不同物理因素的关系以图表的形式展示出来。研究发现,随着雷诺数、磁效应以及在 C2H6O2 中加入 Au 和 Ag NPs 的影响,轴向和漩涡速度轮廓下降。此外,混合纳米流体的能量曲线随着雷诺数、热弛豫因子和 NPs 体积摩擦的影响而下降。

Optimized framework numerical solution for swirling hybrid nanofluid flow with silver/gold nanoparticles on a stretching cylinder with heat source/sink and reactive agents
The heat and mass transportation for nanofluid across a swirling cylinder under the actions of magnetic effects and Cattaneo–Christov heat flux is reported in the current analysis. The objective of this study is to examine the energy and mass transmissions through hybrid nanofluid under the influence of heat source/sink and reactive species. The hybrid nanoliquid has been prepared by the dispersion of silver (Ag) and gold (Au) nanoparticles (NPs) in the base fluid ethylene glycol (C2H6O2). The flow phenomena are expressed in the form of nonlinear partial differential equations and are converted to a nondimensional form, by employing the similarity substitution. For the computational estimation of the problem, the parametric continuation method is employed. The demonstration of velocity, mass, and energy outlines versus distinct physical factors is exposed in the form of figures. It has been perceived that the axial and swirling velocity outline drops with the influence of the Reynolds number, magnetic effect, and the insertion of Au and Ag NPs in C2H6O2. Furthermore, the hybrid nanofluid energy curve declines with the effect of the Reynolds number, thermal relaxation factor, and the volume friction of NPs.
