Abstract
Nanofluids can be engineered as per requirements and have applications in microelectronic, therapeutic activities, hybrid-mechanical machineries, aeronautics zones, thermonuclear storehouses, shielding of miscellaneous engines etc. Here, the aspects of new mass flux theory in magneto Carreau nanofluid with convective and variable connectivity have been studied. Additionally, nonlinear properties of mixed convection are examined. The shear thinning-thickening properties are analysed by utilising bvp4c algorithm for influential variables. The fluid temperature increases with thermophoresis and variable conductivity parameters. The outcomes of thermophoresis and Brownian motion parameters have conflicting influences on concentration field.
