Unsteady mixed convection in a porous media filled lid-driven cavity heated by a semi-circular heaters

A computational study has been performed on natural convection heat transfer and fluid flow in a porous media filled enclosure with semi-circular heaters by using finite element method. The ceiling of the cavity moves with a constant velocity and it is insulated. Temperature of vertical wal...
