Abstract : The transport properties of hydrogen are calculated for a pressure range from 10 to the minus 6th power (atm) to 100 (atm), and at temperatures up to 10 to the 6th power (K). The lower temperature limit is taken where the equilibrium gas mixture contains less than 1% molecular hydrogen. The Boltzmann formalism, which assumes binary collisions in the expressions for the transport properties of gas mixtures, is applied. Theoretical values, supported by experimental data whenever possible are used for the atom-atom, atom-ion, and atomelectron collision cross sections. For Coulomb force interactions between charged particles, the Debye length is used as cutoff distance. The collision integrals for all interactions are computed. Values of viscosity, thermal, and electrical transport coefficients, as well as the thermoelectric coefficients are calculated. (Author)
