概要

• 論文の詳細を見る

• An experimental study was carried out to make clear heat transfer characteristics in flow boiling of binary mixture, HFC-134a and HCFC-123, in a uniformly heated horizontal tube. Experiments were run at a pressure of 0.6 MPa both for pure fluids and mixture in the ranges of heat flux 10-50 kW/m^2, vapor quality 0-0.8 and mass flux 150-600 kg/m^2s. Heat transfer coefficients of mixture were less than the interpolated values between pure fluids both in the low quality region where the nucleate boiling is dominant and in the high quality region where the convective evaporation is dominant. However there is no significant difference in pressure drop between mixture and pure fluids.
