Variable Thermal Conductivity of Sutterby Nanofluid flow: a Numerical Study

The current research focuses on the impact of variable thermal conductivity on electro-magnetohydrodynamic (EMHD) flow of a Sutterby nanofluid in a Darcy-Forchheimer porous media with a stretching sheet. The impacts of thermal radiation and Christov-Cattaneo heat flux model are also considered in the study. The similarity approach is used to transform the governing mathematical model into a set of nonlinear ODEs which are then numerically solved by applying the BVP4C method. The detailed parametric studies are performed to provide more insights into the fluid flow and heat transfer behavior. It is found that the increase in magnetic field and velocity slip parameters decreases the fluid velocity. Also, the rise in the variable thermal conductivity parameter increases the temperature profile. The impacts of several controlling parameters on the velocity, temperature, concentration, skin friction coefficient, heat transfer rate, and Nusselt number are discussed and illustrated graphically and in tabular form.
