Nanoliquids via diffusing less quantity of nanometer-sized elements in base liquids can extraordinarily upsurge heat transport along with thermal functioning of heat exchanging systems. Such liquids are utilized in various fields for illustration liquid fuel, energy storage and absorption, heat-mass transport and lubricating materials. Thus, we aimed to formulate and scrutinize the nanoliquid hydromagnetic flow by permeable convected cylinder. Rheological expressions of Jeffrey liquid are considered to develop flow formulation. Buongiorno model featuring thermophoresis and Brownian diffusions is under consideration for modeling and analysis. Nonlinear version of thermo-solutal buoyancy forces is also a part of this study. Robin conditions, dual stratification and radiation effects are accounted to capture the analyze the heat transport characteristics. Homotopy concept yields convergent solutions of modeled non-linear differential systems. In addition, dimensionless factors are elaborated in detail through graphical and tabular results. We examined reduction in liquid temperature along with concentration subjected to higher thermal/concentration stratification factors.

热-溶质罗宾条件在分层和磁流体动力学下的热辐射纳米流体中的重要性

纳米液体通过在基液中扩散较少量的纳米级元素可以极大地促进热传输以及热交换系统的热功能。此类液体用于各种领域,用于说明液体燃料、能量存储和吸收、热质传输和润滑材料。因此,我们旨在通过可渗透对流圆柱体来制定和审查纳米液体水磁流。Jeffrey 液体的流变表达式被认为是开发流动公式。以热泳和布朗扩散为特征的 Buongiorno 模型正在考虑用于建模和分析。热溶性浮力的非线性版本也是这项研究的一部分。罗宾条件,考虑到双重分层和辐射效应,以分析热传输特性。同伦概念产生建模非线性微分系统的收敛解。此外,通过图形和表格结果详细阐述了无量纲因素。我们检查了液体温度的降低以及受更高热/浓度分层因素影响的浓度。
