Title: Thermal conductivity of gaseous 1,1,1,2,3,3,3-heptafluoropropane (HFC-227ea)

Abstract

The thermal conductivity of gaseous 1,1,1,2,3,3,3-heptafluoropropane (HFC-227ea) is reported over the temperature range from 13.87 to 68.58 C at pressures up to 1.289 MPa. A transient hot-wire instrument with two anodized tantalum wires was used as the heat source. The uncertainty of the results is estimated to be less than {+-}3%. The results are correlated as a function of temperature and density. The thermal conductivity of the dilute gas and the saturated vapor are obtained by extrapolation.
