Highly accurate transport properties of helium-4, helium-3, and their binary mixtures by ab initio potential

• The best ab initio potential was used to study the most important transport properties of helium.
• Highly accurate transport properties of helium were presented from 100 to 10,000 K.
• Ab initio transport properties of this work can be used as standard values in many applications.

A helium–helium interatomic potential determined from quantum–mechanical ab initio calculations by Przybytek et al. has been used in the framework of the classical kinetic theory to calculate the transport properties of helium. The viscosity, thermal conductivity, diffusion coefficient, and thermal diffusion factor were calculated for helium-4, helium-3, and their binary mixtures at low density between 100 and 10,000 K. The predicted results of this work are listed in the Appendix, which are more accurate than the corresponding measured quantities over a wide temperature range.
