【Abstract】 The paper reports the measurements of the thermal conductivity of gaseous HFC32 over the temperature range 254.51K to 341.76K near the saturation line. The thermal conductivities were measured in a transient hot-wire instrument employing two anodized tantalum wires as the heat source with an uncertainty of 1%. The resuilts were correlated as a function of temperature for engineering use.更多还原
