Comparison of the results of prediction of transport coefficients of sodium vapor with experimental data
Annotation
The interatomic interaction potentials derived from new precision spectroscopic data are used to calculate averaged collision cross sections of two sodium atoms. The coefficients of viscosity and thermal conductivity of sodium vapor at temperatures from $700$ to $2500$ K and pressures from those corresponding to monatomic rarefied gas to the saturation curve (but not exceeding $1$ MPa) are predicted. The prediction results are compared with the available experimental data about the transport coefficients of sodium vapor. Possible reasons for observed systematic discrepancy are discussed.
