Summary:Impact of electric-field with Fe3O4 nanoparticles transportation through porous cavity with lid walls is examined. The ethylene glycol as pure fluid with nanoparticles shape and radiation are used. The characteristics of testing fluid strongly rely on voltage and nanoparticles' shape. The CVFEM is utilized to obtain numerical results aftermaths. Plots are acquired for voltage, radiation and nanoparticles' shape. Outcomes demonstrate that higher values of permeability lead to greater Nusselt number. It is also found that convection enhances with rise of electric force. •Numerical simulation of nanoparticle migration within a porous media was studied.•Non-Darcy mode was applied to employ porous terms.•As Da augments, heat transfer augments•Nu declines with augment of electric field.
