Calculation of hydrogen's thermal conductivity at moderate and high densities

At high densities, beyond the range of the RF theory, a residual function for hydrogen's thermal conductivity has been extracted according to the corresponding states function which where used to calculate the thermal conductivity of supercritical gases which is valid over a wide temperature and pressure ranges. The measured values are in good agreement with data given in the literature. It is worth nothing that the available thermal conductivity data of high accuracy cover the restricted temperature range up to 1500 K and pressure up to 100 MPa and our calculation of this property is limited to that range.
