The thermal conductivity of gaseous trifluoroiodomethane (CF3I) is rep
orted over the temperature range -6.50 degrees C to 63.55 degrees C at
pressures up to 1000 kPa with an uncertainty of 3% using a transient
hot-wire instrument employing two anodized tantalum wires as the heat
source. The results were correlated as a function of temperature and d
ensity. The values for the thermal conductivity of the dilute gas and
the saturated vapor are obtained by extrapolation.
