Abstract

New experimental data on the thermal conductivity of butane are reported that allow improved correlations to be developed. Previous correlations have beenlimited by a lack of thermal conductivity data for the vapor and compressed liquid at temperatures below 300 K and near the critical point. In additionsignificant discrepancies were noted in the high-temperature dilute-gas thermal conductivity. These new experimental data covering a temperature rangefrom the triple point at 135.86 K to 600 K and a pressure range of 0. I to 70 MPa, are used together with the previously available data to develop improvedcorrelations for the thermal conductivity of butane. The quality of the new data is such that the thermal-conductivity correlation for butane is estimated to havean uncertainty of about 3 % at a 95 % confidence level, with the exception of state points near the critical point and the dilute gas, where the uncertainty of thecorrelation increases to 5%.
