Abstract

Shear viscosities of hydrogen (H2) and helium (He) fluids are investigated at extended regions of temperature and pressure using an improved equation of state, in which the the long-range attractive forces are incorporated into the formalism via the double Yukawa (DY) potential fitted to the empirical H2 and He potentials. Quantum effects, which become paramount at low temperatures, are taken into account through a first-order quantum correction based on the Wigner-kirkwood expansion. The dimerization of H2 is treated as a hard convex body for which an equation of state can be derived based on the scaled particle theory.
