Tables of Thermodynamic Properties of Air in Chemical Equilibrium Including Second Virial Corrections from 1500k to 15,000k

摘要

Tables for the thermodynamic properties for air are presented which take into account the effect of dissociation and ionization and the limiting-law Debye-Huckel and second virial corrections upon the thermodynamic properties and the equilibrium compositions. Values are tabulated from 1500K in steps of 100K to 15,000K at close spacings in the logarithm of the density (log rho/rho sub o = -7. (0.2)2.2) for the compressibility factor Z Z = PV/RT; the dimensionless functions for: internal energy, E/RT; enthalpy, H/RT; entropy, S/R Xi; log P(atm) and Z = sigma C sub i. The underlying equations and the input data are discussed briefly. The effects of the real gas corrections on the equilibrium properties are illustrated graphically. The equilibrium composition is given for selected temperatures over the tabulated density range. The wide range of temperatures and densities over which the thermodynamic properties have been tabulated make the tables useful in a variety of engineering design and test programs, and in scientific research and development.
