Abstract
Nanomaterial transportation within a closed tank under the role of space-dependent Kelvin force was analyzed numerically in current article. With purpose of augmentation of cooling rate, two approaches were employed in this system: (1) insertion of wire near the inner surface; (2) addition of nano-sized material inside the water. The geometry of tank includes wavy hot wall. Finding the solution for this model has been done via CVFEM. The final equations contain vorticity definition and there is no term for pressure source term. Verification test shows nice agreement according to comparison the outputs with data of previous publication. Single phase technique for calculation of nanomaterial features were applied and utilizing iron oxide nano-sized particles makes cooling rate to augment about 17.1%. Without FHD, increase of gravity force makes the velocity of testing fluid to augment and Nu enhances around 70.37%. With applying FHD, the strength of vortexes augments and Nu elevates about 28.61%.
