Testing intermolecular potential functions using transport property data. Part 1.—Viscosity of hydrogen from 273 to 1060 K

Abstract

The viscosity of hydrogen has been measured at eight temperatures from 273 to 1060 K, using a capillary-flow viscometer. The results have been used to test the repulsive part of a recently formulated H2/H2 intermolecular potential function, obtained from molecular-beam measurements. Agreement between the experimental and predicted values for viscosity is within 3.5 %, which corresponds approximately to the combined quoted uncertainties in the two sets of data. However, if the value of the distance parameter of the potential is reduced by about 1.5 %, the agreement obtained is within 0.75 % over the whole temperature range. This modified potential function gives better agreement with the available higher temperature viscosities and second virial coefficients.
