Simulation of MHD impact on nanomaterial irreversibility and convective transportation through a chamber

In the current investigation, numerical method (CVFEM) was selected to show the impact of Lorentz force on transportation of operate fluid (water with a mixture of Fe3O4 and CuO). Adding the source terms associated with MHD (magneto-hydrodynamic) and porous zone leads to a mathematical model and utilizing vorticity formulation can make the equations to simplify. Not only the viscous and heating irreversibility but also permeable and magnetic terms were calculated. Nu and Be have been measured and based on results, two correlations were defined. As permeability and buoyancy effects augment, the velocity of operating fluid augments while lower velocity will be reported if Lorentz forces increases. S-gen,S-th decreases about 44% with augment of Ha but it augments about 100% with grow of Ra. Velocity augments about 75% with rise of Da while it declines about 50% with the growth of Ha. Intensification of Ha causes Nu to reduce about 7.85% while Be augments about 13.62%. As Da enhances, Be declines about 5.79 while Nu enhances about 49.11%. With the growth of Ra, Be decreases about 49.79% while Nu augments about 392%.

Automated summary
