Two distinct correlations based on the results of a detailed H2-He transport property analysis have been developed. The first correlation provides the transport properties of the individual species with mixtures properties computed by existing semi-empirical methods. The second correlation produces the equilibrium mixtures properties for viscosity and both the frozen and total values for the Prandtl number and the thermal conductivity. The validity of the two correlations is demonstrated by comparison with results of the detailed analysis. The influence of transport properties on predicting the n-injection convective and radiative heating rates for Jovian entry conditions is demonstrated. (Kursetz)
