This paper presents new wide-ranging correlations for the thermal conductivity of n-hexadecane based on critically evaluated experimental data. The correlations are designed to be used with a recently published nist-equation of state that is valid from the triple point up to 700 K and pressures up to 50 MPa. We estimate the uncertainty at a 95% confidence level to be 3.5% over the aforementioned range, with the exception of the dilute-gas range where the uncertainty is 2.7% over the temperature range 583 to 654 K. The correlation behaves in a physically reasonable manner when extrapolated to the full range of the nist-equation of state, but the uncertainties will be larger outside of the validated range, and also in the critical region.
