| Abstract: | Particle number distribution of high temperature air are obtained in the range of temperature of 2000~30000 K and pressure of 0.1~500 MPa by solving the Saha equation with considering dissociation, ionization, and oxidation in local thermodynamic equilibrium. And then, specific heat, entropy, and enthalpy have been computed in detail. |
| Keywords: | nitrogen oxygen dissociation and ionization degrees specific heat entropy enthalpy |
