Abstract:
Here, the effect of rotating cavity filled by porous materials exposed to two variable magnetic fields on the heat transfer natural convection is investigated. The two hot semicylinder are cooled by the heat transfer through the porous medium. The two magnetic fields affect the nanofluid flow and the heat transfer of the natural convection inside the porous cavity. The characteristic equations related to the fluid flow including the continuum equation, momentum and two nano-fluid and the solid-state matrix energy equations of the porous medium have been solved to predict the problem behavior. The influence of the cavity rotation angle on the streamlines and temperature field is investigated. The results show that increasing the rotation angle has oscillatory effects on the magnitude of the streamlines. For the rotation angles = 20 and = 100 the heat transfer via both phases is intensified. The rotation of the cavity depends on how the magnetic field-induced Lorentz and Kelvin forces amplify or weaken the heat transfer, thereby altering the Nusselt number of both phases of porous medium.
