Numerical investigation of nanofluid transportation in a curved cavity in existence of magnetic source

Thermal radiation impact on magnetic nanofluid heat transfer in a curved cavity is studied. Impact of external magnetic source is taken into account. Innovative numerical method is chosen namely CVFEM. Impacts of radiation parameter ( Rd ) , Rayleigh ( Ra ) , Hartmann ( Ha ) numbers and volume fraction of Fe3O4 ( ϕ ) on hydrothermal treatment are examined. Results indicate that temperature gradient enhances with augment of Ra , ϕ , but it reduces with rise of Rd , Ha . Lorentz forces cause the nanofluid velocity to reduce and augment the thermal boundary layer thickness. Impact of radiation becomes stronger for higher buoyancy forces.
