ON THE VISCOSITY OF DISSOCIATED AIR

Abstract

Using a particular set of interaction parameters, it is shown that the viscosity of dissociated high-temperature air is well represented by a simple formula which is a perturbation from the pure-molecule result. To this order, information about atom-atom interactions is not needed. The perturbation formula is then used to show that there is no point in calculating the effect of composition on viscosity unless the atom-molecule interaction parameters are known within a very few per cent. Finally, it is noted that the composition effect on boundary-layer transport properties stems chiefly from the dilatation factor in the state equation, tending to justify calculation of viscosity on a pure-molecule basis.
