SIMULATION OF TROMBE WALL IN BAGHDAD ATMOSPHERE

A finite volume method was used to solve the fully Navier-Stokes and energy equations for the problems of turbulent flow and heat transfer characteristics through room with Trombe wall. The Trombe wall system is applied to four materials : concrete, light concrete, masonry, and also paraffin wax type (n-eicosene) to heat a room whose dimensions are (3*2*2)m in climatic conditions of Baghdad in winter months namely, (Dec, Jan, Feb). The thickness of the wall was changed for every material from the above mentioned materials. Three inlet velocities (0.5, 2, 4) m/s was applied on this system. The velocity and temperatures distribution are predicted.
