Effect of nanospray on hydrodynamic cylindrical film flow of Sutterby–Casson nanoliquids: A renewable energy application

Abstract

Renewable energy is the most prominent energy source due to its industrial and technological needs. A computational examination is performed to explore the result of the nanospray on the film flow of Casson and Sutterby nanofluids over a cylindrical surface. Due to the effective thermal conductivity of graphene oxide, the water–graphene oxide nanofluid is considered in the existence of radiative heat, Catteneo–Christove heat flux, and hydrodynamic effects. A mathematical model is established and resolved numerically by applying appropriate similarities. Simultaneous results are obtained for Sutterby and Casson nano models. The impact of considered physical features on the flow and heat transmission of both liquids is studied with the help of pictorial and mathematical outcomes. The heat transmission rate of the Casson nanoliquid is higher than the Sutterby nanoliquid. Hence, the fluids with Casson rheological nature are helpful in heat transfer applications. Both liquids’ flow and heat transport rate can be regulated by adjusting the film thickness.
