Simulation of nanofluid flow and natural convection in a porous media under the influence of electric field using CVFEM
چکیده انگلیسی
Fe3O4-Ethylene glycol nanofluid Electrohydrodynamic flow and natural convection heat transfer in a porous medium is simulated numerically. Thermal radiation term is added in energy equation. Properties of nanofluid are considered as a function of supplied voltage and shape of nanoparticles. The bottom wall is considered as positive electrode. Control Volume based Finite Element Method is employed to obtain the outputs which are the roles of radiation parameter (Rd), Darcy number (Da), nanofluid volume fraction (ϕ), Rayleigh number (Ra) and supplied voltage (Δφ). Results show that maximum Nusselt number belongs to Platelet shape Fe3O4 nanoparticles. Nusselt number is an increasing function of Darcy number, supplied voltage and Rayleigh number.
