SINOPSIS

Radiative heat source impact on nanofluid electrohydrodynamic flow has been displayed numerically using CVFEM. Fe3O4-ethylene glycol nanofluid was employed considering the electric field effect on its viscosity. Different shapes of nanoparticles have been considered, i.e., spherical, platelet, cylinder, and brick. The positive electrode is the lower wall. The physical behavior of permeability, Coulomb forces, lid velocity, the volume fraction of nanofluid, and radiation parameter have been discussed numerically and graphically. A graphical comparison is also shown to ensure that the results obtained are correct. It is found that the Darcy number and Coulomb tend to enhance the distortion of isotherms. Furthermore, thermal radiation also tends to augment the temperature gradient closer to the lower wall.
