Numerical analysis was applied to a simplified two dimensional Ondol hearing system which consists of heating space with radiant and convective heating floor panel, flue channel in the midway and rectangular underground region at the bottom. These three components constitute a system thermally coupled at the top and the bottom interfaces of the flue channel.
Investigated in the present paper are effects with variations of the Reynolds numbers of 100, 200 and 300, Grashof numbers of 0.1×106 and 0.3×106 and aspect ratios of 15 and 20 on the heat transfer and fluid flow characteristics in Ondol heating model by computer simulation.
