Abstract : Results are given for equilibrium properties behind incident and reflected normal shock waves in CO2-N2-He mixtures wherein the gas may be vibrationally excited but not chemically reacting. A rapid numerical iterative analysis is described, and the results are given in simple graphical form for convenient use in shock tube and shock tunnel experiments. The results are anticipated to be of particular use in determining reservoir conditions for shock tunnel experiments dealing with vibrational population inversions in rapidly expanding mixtures.
