NUMERICAL STUDY OF TRANSIENT HIGH RAYLEIGH NUMBER CONVECTION IN AN ATTIC-SHAPED POROUS LAYER.

Scaling arguments and numerical analysis are used to document the transient and steady-state regimes of natural convection in a triangular porous layer cooled from above (along the sloping wall). The numerical simulations are conducted in the high Rayleigh number domain, Ra equals 100, 1000, where Ra is the Darcy-modified Rayleigh number based on height, H.
