Abstract

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.
