Abstract
Abstract In this research, heat transfer along with entropy of an unsteady non‐Newtonian Casson nanofluid flow is studied. The fluid is positioned over a stretched flat surface moving non‐uniformly. The nanofluid is analyzed for its flow and heat transport properties by subjecting it to a slippery surface, which is convectively heated. The governing mathematical equations describing the physical characteristics of Casson nanofluid flow as well as heat transfer models are abridged under boundary layer flow assumptions and Roseland approximations. Governing equations of flow problem are formulated in partial differential equations. A computative technique, Keller box accustomed to find the self‐similar solution of equations that converted into ordinary differential equations (ODEs) by using proper transformations. Two different classes of nanofluids, copper‐methanol (Cu–MeOH) and titanium‐methanol (TiO 2 –MeOH) are considered for our analysis. Significant results of various parameters in flow, heat, skin friction, Nusselt number and entropy analysis are elaborate graphically. The remarkable finding of this work is that the Cu–MeOH nanofluid is better transfer source as compared to TiO 2 –MeOH nanofluid.
