In current investigation, ferrofluid circulation and energy transport inside a wavy-walled porous enclosure are modeled considering radiation and EHD effects. The finite volume method is employing for simulation of EHD circulation structures and thermal transmission. Properties of working fluid depend on the electric field and nanosized solid particles concentration. Impacts of thermal radiation, nanoparticles shape, and volume fraction are considered in governing equations. Distributions of unknown functions are received for various voltage, permeability, radiation parameters, nanoparticles’ shape and concentration. Results have shown that platelet form leads to the strongest convective circulation. An amplification of electric force characterizes a diminution of the boundary layer thickness. Greater permeability of the porous medium characterizes the strongest convective circulation and thermal transmission.
