Three-dimensional coupled flow and heat transfer in non-newtonian magnetic nanofluid: An application of Cattaneo-Christov heat flux model

This article has been fine-tuned with studying the three-dimensional laminar flow of a magnetic liquid over a stretching sheet with the influence of thermal radiation and Cattaneo-Christov heat flux. Moreover, this article mainly focuses on moderate saturation magnetization and low Curie temperature. The dynamics of propylene glycol-paraffin wax nanofluid + water mixture and zinc oxide (ZnO)-SAE50 Nano-lubricant fluid flow is examined. The modeling equations are converted into non-linear ordinary differential equations (ODEs) using the required similarity transformations. The Runge-Kutta-Fehlberg fourth-to-fifth order (RKF-45) technique is used to solve the resultant non-linear ODEs numerically. Numerous regulating factors that affect the velocity and temperature profiles are examined via graphs. Research of the present study has shown that Deborah number accounts for the decelerating radial and tangential flow of both nanolubricant and nanofluids. The ZnO-SAE50 Nano-lubricant flow shows high heat transfer and increases faster followed by propylene glycol - water mixture + paraffin wax nanofluid flow for the increase in values of radiation parameter. The ZnO-SAE50 Nano-lubricant flow shows high heat transfer rate than propylene glycol-water mixture-based nanoliquid for rising values of radiation parameter.
