Abstract
For estimating impact of electric force on treatment of ferrofluid, new numerical techniques have been involved in current article. The operate fluid contains iron oxide as additive in nano-sized with various shapes. The fraction of particles with nano-sized is smaller than 0.06, and for involving such effect, properties of carrier fluid have been changed based on empirical formulation with neglecting the slip velocity. There were two moving wall at the left and bottom surfaces which has highest temperature and voltage. The domain was porous and related terms were added in momentum according to non-Darcy assumption. Combined method of FVM and FEM was selected to find the solution for this problem. As electric force applied, the nanofluid can move with higher speed and two primary vortex convert to one stronger vortex. Nu augments about 125.52% and 65.43% with rise of voltage when Da = 1e2 and 1e5. Utilizing media with higher permeability lead to stronger collision with wall and Nu elevates about 113.29%. Replacing nanoparticle with higher shape factor instead of sphere, Nu augments about 3.69%.
