Abstract


This work is related to the determination of the local thermodynamic equilibrium (LTE) data of 90.5% air and 9.5% CH4 mixture. The results of chemical composition, thermodynamic properties and transport coefficients are presented for temperatures (300 K to 30 kK) and pressure (1 and 10 bars) or mass density (0.1481 and 1.111 kg.m−3). The chemical composition is determined using the mass action law. Input data come from the NIST and JANAF sites. For pressure equation, Debye-Huckel’s first order and virial’s second order corrections are used in the equation system to take into account the different particle interactions. For the considered mixture (90.5% air and 9.5% CH4) the properties are compared to those of pure air.

Keywords
