CVFEM for magnetic nanofluid convective heat transfer in a porous curved enclosure

The influence of a magnetic field on the nanofluid hydrothermal behavior in a porous curved enclosure is examined. A constant heat flux condition is considered for the inner wall. A new numerical approach is applied, namely the Control Volume-based Finite Element Method (CVFEM). Impacts of Darcy (Da), Rayleigh (Ra), Hartmann (Ha) numbers and volume fraction of Fe3O4 (phi) on the hydrothermal treatment are graphically depicted in figures. Results reveal that the thermal boundary thickness increases with increasing Ha while it decreases with increasing Ra, phi, Da. Nanofluid motion decreases with increasing the Hartmann number but it increases with increasing the Darcy number. At low Darcy and high Hartmann numbers, impact of adding Fe3O4 is more effective.
