Abstract:
Empirical equations were obtained for equilibrium dissociating and ionizing air and nitrogen for temperatures up to 15,000°K and in the entropy range 1.42 ≤ log (S/R) ≤ 2.06. The corresponding density range is approximately 10-6 to 102 amagats. The density ρ (p,S), enthalpy H (p,S), compressibility factor Z (p,S), and speed of sound a (p,S) are presented in equation form and as an IBM Fortran subroutine program. The errors in each empirical surface are indicated.
