Calculations and curve fits of thermodynamic and transport properties for equilibrium air to 30000 K

摘要: A self-consistent set of equilibrium air values were computed for enthalpy, total specific heat at constant pressure, compressibility factor, viscosity, thermal conductivity, and Prandtl number from 500 to 30,000 K over a range 10(exp -4) atm 2) atm. The mixture are calculated the transport thermodynamic properties individual species provided in recent study by authors. concentrations species, required relations, obtained free energy minimization calculation procedure. Present calculations based on an 11-species model. For pressures less than -2) temperatures about 15,000 greater, N(++) O(++) become important, consequently, they included determining various properties. curve fitted as function temperature value pressure. These fits reproduce within 5 percent entire considered here provide efficient means computing flowfield air, elemental composition remains 0.24 oxygen 0.76 nitrogen mass.
