|제목(영문)||Study on the Flow of Bripuette Gas in the Ondol Heating System|
|초록||Natural draft and flow which low temperature moist gas produces in the chimney of an Ondol heating system were numerically analysed.
Among several factors involved inlet gas temperature has the strongest influence on the chimney performance and then next specific humidity of the gas. Thermal conductivity of the chimney wall, however, has little influence on the performance of such a low temperature chimney.
Under given flow conditions there exists an optimum chimney height which gives a maximum flow rate for a given chimney diameter. This optimum value of chimney height increase with increases in chimney diameter, inlet gas temperature and specific humidity.
