Transport properties in the Jovian atmosphere

Transport properties in a Jupiter‐like atmosphere (89 mol % hydrogen and 11 mol % helium) are obtained by using the method of the kinetic theory of gases. The transport collision integrals are calculated by fitting various two‐body semiempirical interaction potentials for which the collision integrals are tabulated to ab initio quantum mechanical calculations of the two‐body interactions. The collision integrals are used to calculate the binary diffusion coefficients, viscosity, and ‘total’ thermal conductivity of the pure gases and the gas mixtures at 1‐atm pressure from 1000°K to 25,000°K.
