A panel and a funnel are sealed by frit material,chemical compound through main sealing furnace at around 450℃ for half an hour in order that those may form a television bulb. 6 bulbs in a row are entered into the main sealing furnace 20 sub-furnaces are connected consecutively composing the entire furnace. The forced convection is induced onto the surface of bulb by the hot air flowing through the fan and perforated plate. A sub-furnace consists of conduit duct, fan and perforated plate. It is inefficient to computationally discretize the perforated plate exactly, which has 210 small holes each sub-furnace. Therefore, the efforts to obtain source term was made in order to substitute flow resistance from the perforated plates inside a sub-furnace. The comparison between the calculation with perforated plate holes and the calculation with porous source term has been shown for a sub-furnace.
