Magnetohydrodynamic flow of dissipative casson-carreau nanofluid over a stretching sheet embedded in a porous medium under the influence of thermal radiation and variable internal heat generation

Abstract

In this paper, finite difference method is used to study the combined effects of thermal radiation, inclined magnetic field and temperature-dependent internal heat generation on unsteady two-dimensional flow and heat transfer analysis of dissipative Casson-Carreau nanofluid over a stretching sheet embedded in a porous medium. In the study, kerosene is used as the base fluid which is embedded with the silver (Ag) and copper (Cu) nanoparticles. Also, effects of other pertinent parameters on the flow and heat transfer characteristics of the Casson-Carreau nanofluids are investigated and discussed. From the results, it is established that the temperature field and the thermal boundary layers of Ag-Kerosene nanofluid are highly effective when compared with the Cu-Kerosene nanofluid. Heat transfer rate is enhanced by increasing power-law index and unsteadiness parameter. Skin friction coefficient and local Nusselt number can be reduced by magnetic field parameter and they can be enhanced by increasing the aligned angle. Friction factor is depreciated and the rate of heat transfer increases by increasing the Weissenberg number. A very good agreement is established between the results of the present study and the previous results. The present analysis can help in expanding the understanding of the thermo-fluidic behaviour of the Casson-Carreau nanofluid over a stretching sheet.

Thermal Radiation Effects on MHD Casson and Maxwell Nanofluids Over a Porous Stretching Surface

“…For the magnetohydrodynamic Carreau and Casson fluids, Kumaran et al [5] have studied the exponential heat source/sink, momentum, and thermal transport over the spinning paraboloid. A study on free convective heat and mass transfer flow through a highly porous medium with radiation, chemical reaction and Soret effect is analysed by Suneetha et al [6] . Sobamowo et al [6] .…”

Sobamowo et al [6] . have looked at the effects of additional control features on the stream and heat transfer qualities to the nanofluids when the base fluid is implanted with the upper and silver nanoparticles.…”

MHD Slip Flow of Upper-Convected Casson and Maxwell Nanofluid over a Porous Stretched Sheet: Impacts of Heat and Mass Transfer

“…The magnetohydrodynamic Carreau and Casson fluids' exponential heat source/sink, momentum, and thermal transport over the spinning paraboloid have all been examined by Kumaran et al, [5]. As the base fluid is implanted with the silver and upper nanoparticles, Sobamowo et al, [6] have examined the impacts of additional control attributes on stream and heat transfer attributes to the nanofluids. Unsteady Carreau-Casson fluids in a solution of dust and graphene nanoparticles with non-Fourier heat flux over a radiating shrinking layer have been explored by Santosh et al, [7].…”
