Calculation of the transport properties of dilute gas mixtures on the basis of model potentials. Mercury–argon system

详细

Interatomic potentials V(Hg–Hg), V(Ar–Ar), and V(Hg–Ar) of atoms in their ground electronic state are analyzed for the technically important mercury–argon dilute gas mixture. The collision integrals are calculated for these potentials, and the transport properties of mercury, argon, and their mixture, such as, viscosity, thermal conductivity, and self-diffusion and mutual diffusion coefficients of compounds, are determined using the molecular-kinetic theory relationships. Detailed tables of properties on five isotherms within a range of 300–2000 K and mixture concentrations of 0.001–0.999 are given. Tables of the properties also contain thermal diffusion factors and Prandtl (Pr) and Schmidt (Sc) numbers. Some specific features in the behavior of properties depending on the composition are considered.
