H211 加熱による物性値変化が対流熱伝達に及ぼす効果 : 低レイノルズ数における円柱からの強制対流の場合(一般講演)
詳細
Concerning on hot wire type temperature and velocity measuring equipments, the effects of thermal properties change on forced convection heat transfer was examined precisely through the measurements of heat transfer ratio from thin metal wire heated in various heat ratio. The results of experiments show that the normalized heat transfer coefficients increases slightly with increase of flow temperature. These results indicate that the variations of thermal properties with large temperature deference alternate the forced convection heat transfer ratio intricately.
