Thermal Radiation Effect on Non-Newtonian Fluid Flow over a Stretched Sheet of Non-Uniform Thickness

Abstract

The influence of thermal radiation on a two-dimensional non-Newtonian fluid flow past a slendering stretching surface is investigated theoretically. Casson and Williamson fluid models are considered with Soret and Dufour effects. The transformed ODEs are solved numerically using the bvp5c Matlab package and dual solutions are executed for Casson and Williamson fluid cases. The influence of various parameters, namely, thermal radiation parameter, cross diffusion parameters and slip parameters on velocity, thermal and concentration distributions are discussed with the assistance of graphs. The local Nusselt and Sherwood numbers are computed and presented through tables. It is observed that the influence of cross diffusion is higher on Williamson flow when equated with the Casson flow.

Nonlinear Rosseland thermal radiation and energy dissipation effects on entropy generation in CNTs suspended nanofluids flow over a thin needle

“…Mohamed et al [16] numerically studied the effects of viscous dissipation on a flow of nanofluid over a moving flat plate. Some recent studies on the heat transfer analysis with and without viscous dissipation effects are reported in [17][18][19][20][21][22][23][24][25][26][27].…”

Impact of dissipative heat and radiative heat on MHD viscous flow through a slandering stretching sheet with temperature‐dependent variable viscosity

“…Considering a slandering stretching sheet and variable viscosity, Babu et al 14 studied MHD dissipative fluid flows and analyzed heat and mass transfer characteristics, and found a rise in temperature due to the influence of the magnetic field, varying viscosity parameter, and heat transfer Biot number. Sharma et al 15,16 and Krishna et al 17 considered MHD nanofluid motion through a slandering extending sheet and observed the effect of varying thickness and melting transferal of heat on it. They saw a decrement in temperature by raising the wall thickness parameter and flow of the boundary layer and heat and mass transfer were nonuniform.…”

A Simulation of Nonlinear Thermally Radiative Hydrodynamic Stagnation Point Flow of Nanomaterial in View of a Stretchable Surface

“…The results of electrically conducted stagnation point Jeffrey nanofluid flow by a stretching surface in view of Joule heating and radiations effects subject to uniform magnetic field is evaluated by Hayat et al [17]. Recently several engineers and mathematician investigated [18][19][20][21][22][23] explored the distinctive features of heat transfer problems and boundary layer flow of non-Newtonian fluids over a stretching surface with different geometry subject to viscous dissipation and Joule heating. Goyal and Bhargava [24] highlighted the impact of velocity slip condition on heat flow of nanofluid over stretching surface with heat reservoir and uniform magnetic field.…”
