Thermodynamic and transport properties of high temperature equilibrium air plasmas have been calculated in a wide pressure (0.01 divided by 100 atm) and temperature range (50 divided by 60 000 K). The results have been obtained by using a self-consistent approach for the thermodynamic properties and higher order approximation of the Chapman-Enskog method for the transport coefficients. Debye-Hukel corrections have been considered in the thermodynamic properties while collision integrals of charge-charge interactions have been obtained by using a screened Coulomb potential. Calculated values have been fitted by closed forms ready to be inserted in fluid dynamic codes.

Abstract
Thermodynamic and transport properties of high temperature equilibrium air plasmas have been calculated in a wide pressure (0.01 divided by 100 atm) and temperature range (50 divided by 60 000 K). The results have been obtained by using a self-consistent approach for the thermodynamic properties and higher order approximation of the Chapman-Enskog method for the transport coefficients. Debye-Hukel corrections have been considered in the thermodynamic properties while collision integrals of charge-charge interactions have been obtained by using a screened Coulomb potential. Calculated values have been fitted by closed forms ready to be inserted in fluid dynamic codes.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
