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...

description |
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 walls is lower
than that of heaters. Results are presented via streamlines, isotherms,
average Nusselt numbers and cross sectional velocity for different governing
parameters such as Richardson number, Darcy number and dimensionless time. It
is observed that both circulation of the flow and heat transfer is strongly
affected with time increment and Darcy number inside the cavity. |
