Inlet (flue gases from furnace)
Velocity inlet
The velocity of the air was 0.3 m/s. The ambient air temperature was 30.1°C, while the heated air from the combustion chamber (flame tip temperature) was measured and inputted from the experiment.
Outlet
Pressure outlet
The gauge pressure was assumed to be zero.
Hot plate
Wall
Stainless steel material was assigned to the hot plate.
Brick wall
Wall
The brick wall external temperature was assigned 30.1°C (which is the same as the ambient temperature).
Furnace internal wall
Wall
Brick material was assigned to the furnace internal walls.
