Soret, viscous dissipation, and thermal radiation effects on MHD free convective flow of Williamson liquid with variable viscosity and thermal conductivity

Abstract

The flow model of heat and mass transport of a Williamson liquid through a porous stretching sheet with radiation, viscous dissipation, Soret effect, and chemical reaction has been explored. The motion starts from the slot to the free stream. The present study is unique, because it examines the flow of a Williamson fluid under the influence of variable viscosity and thermal conductivity. The Williamson fluid term as added to the momentum and energy equation is considered in a nonlinear form as compared with other studies in literature. The flow model is a set of coupled highly nonlinear partial differential equations that are simplified and lead to coupled nonlinear total differential equations by employing sufficient similarity variables. The simplified equations are later solved by utilizing the spectral homotopy analysis method. Our experiment shows that the injected variable viscosity, together with thermal conductivity, has a great impact on the fluid profiles. An increase in the Williamson parameter (β) leads to a decrease in the thickness of the hydrodynamic thermal layer. Our numerical calculations were compared with earlier published work, and they were discovered to be correct.

“…Shilpa et al 21 investigated mixed convection flow of Casson in occurance of amplification in a porous medium. Cletus et al 22 studied the Williamson liquid along the stretching porous sheet in existence of Soret effect, viscous dissipation, chemical reaction and radiation to transfer mass and heat. Spectral homotopy analysis method have been implemented to resolve the obtained equations.…”
