Key words: oxygen, nitrogen, water vapor, carbon monoxide, carbon dioxide, hydrogen, real-gas thermal and caloric equations of state
Thermal and caloric equations of state (EOS) of main species in gaseous mixtures used in the calculations of various gas dynamic processes, including combustion and detonation as well as internal ballistics, are presented in the analytical formulation. The EOC contain a relatively low number of parameters and exhibit the approximation error which is in average less than 1 % at temperatures from 500 to 2000 — 2500 K and at densities up to the critical density.
