Abstract
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 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 equation of state, but the uncertainties will be larger outside of the validated range, and also in the critical region.
