Enhanced thermal conductivity of the Carreau nanoliquid by using Maxwell/Xue nanomodels.

AbstractA numerical investigation is performed to scrutinize the enhanced thermal transmission of Carreau nanoliquid above an incessantly moving thin needle in the occurrence of nonuniform heat rise/fall effects. The arising system of nonlinear coupled equations is exercised numerically by employing a suitable numerical scheme, i.e. bvp5c Matlab solver. The prime motive of this research is to determine the effectual thermal conductivity of the nanoliquid by using Maxwell/Xue models to achieve enhanced energy transmission. The stimulus of pertinent constraints upon the flow factors, viz. velocity and thermal gradients, are illustrated through plots. Also, the wall friction and energy transmission rate are bestowed <italic>via</italic> plots and tabular values. The outcomes reveal that the Xue nanomodel augments the thermal transmission rate of the nanofluid to a greater extent than the Maxwell nanomodel. This research holds potential for applications in geothermal power production. [ABSTRACT FROM AUTHOR]
