Magnetohydrodynamic migration of nanomaterial within a cavity with involvement of hybrid nanoparticles
Abstract
To examine the hybrid nanomaterial transportation within a permeable region, a numerical approach was applied. The permeable domain was filled with a mixture of water with hybrid nanomaterial (Fe3O4+ MWCNT). The wavy below wall experiences uniform flux but the top circular wall maintains at cold temperature. Magnetic field in x-direction was applied and non-Darcy formulation was applied for applying permeability effect. Gravity forces help the transportation of hybrid nanomaterial and magnetic forces reduce the speed of nanomaterial. Imposing nanomaterial can decline the irreversibility. For simulation of equations, CVFEM was applied and Bejan and Nu numbers were calculated. Verification test depicts the nice agreement and contours for irreversibility have been presented. By imposing Ha, the Be augments about 4.36% while Nu declines around 13.32%. By selecting greater Da, the Nu intensifies around 8.95% while Be declines about 4.35%. Nu elevates around 93.78% with an augment of Ra while Be drops around 52.75%.
