摘要:

Forced convection heat transfer of ethylene glycol based nanofluid with Fe3O4 inside a porous medium is studied using the electric field. The control volume based finite element method (CVFEM) is selected for numerical simulation. The impact of the radiation parameter (Rd), the supplied voltage (△ψ), the volume fraction of nanofluid (φ), the Darcy number (Da), and the Reynolds number (Re) on nanofluid treatment is demonstrated. Results prove that thermal radiation increases the temperature gradient near the positive electrode. Distortion of isotherms increases with the enhance of the Darcy number and the Coulomb force.
