Abstract
In this study, an investigation has been carried out to analyze the impact of electro-osmotic effects on the Darcy–Forchheimer flow of Casson nanofluid past a stretching sheet. The energy equation was modelled with the inclusion of electro-osmotic effects with viscous and Joule dissipations. The governing system of partial differential equations were transformed by using the suitable similarity transformations to a system of ordinary differential equations and then numerically solved by using the Runge–Kutta–Fehlberg method with a shooting scheme. The effects of various parameters of interest on dimensionless velocity and temperature distributions, as well as skin friction and heat transfer coefficient, have been adequately delineated via graphs and tables. A comparison with previous published results was performed, and good agreement was found. The results suggested that the electric and Forchheimer parameters have the tendency to enhance the fluid velocity as well as momentum boundary layer thickness. Enhancements in temperature distribution were observed for growing values of Eckert number. It was also observed that higher values of electric field parameter diminished the wall shear stress and local Nusselt number.
Highlights
The flow driven by a stretchable sheet is significant because the ultimate desirable output is heavily impacted by the rate of stretchable and heat transport at the surface, representing wide applicability in industrial and manufacturing procedures
The system of governing equations has been converted to dimensionless differential equations by employing similarity transformations; the shooting technique was implemented to derive numerical solutions and the relevant data for wall shear stress and heat flux
The impact of various physical parameters such as the porosity factor, electric field parameter, Casson fluid parameter, and Prandtl and Eckert numbers on flow profiles are discussed in detail
Summary
The flow driven by a stretchable sheet is significant because the ultimate desirable output is heavily impacted by the rate of stretchable and heat transport at the surface, representing wide applicability in industrial and manufacturing procedures. Mukhopadhyay [3] discussed the effect of heat radiation on the unsteady flow of Casson liquid generated by a stretched sheet exposed to blowing/suction. Mustafa et al [6] inspected the heat transport and flow of the boundary layer of a Casson fluid along a movable flat plate with a paralleled free stream and addressed the question analytically, utilizing the homotopy analysis method. Ibrahim and Makinde [7] reported the numerical outcomes of electrically showing the slip flow of Casson nanofluid produced while a stretching sheet was under the effect of convective boundary condition utilizing similarity alterations.
