Abstract
Electrohydrodynamic Fe3O4- Ethylene glycol nanofluid forced convection is simulated in existence of thermal radiation. The porous lid driven cavity has one moving positive electrode. Single phase model has been applied to simulate nanofluid behavior. Control Volume based Finite Element Method is employed to obtain the results which are the roles of Darcy number , radiation parameter , Reynolds number , nanofluid volume fraction and supplied voltage . Results depict that maximum values for temperature gradient is obtained for platelet shape nanoparticles. Nusselt number enhances with rise of Darcy number and supplied voltage. Convection mode enhances with increase of permeability of porous media and nanofluid volume fraction but it decreases with rise of Hartmann number.
