IGE Model: An Extension of the Ideal Gas Model to Include Chemical Composition as Part of the Equilibrium State

Algorithm 1

Set 𝛼=0.4

Specify the specific enthalpy ℎ_∘ and pressure 𝑝 of the reactants

Compute the temperature as a function of ℎ_∘ and 𝑝,𝑇=𝑓(ℎ_∘,𝑝)

Compute the equilibrium distribution of the product mixture

 according to 𝑇 and 𝑝

Repeat

 Set 𝑇^=𝑇

 Compute the thermodynamic state of this product mixture

 based on ℎ_∘ and 𝑝 giving a new temperature 𝑇

 Set 𝑇=𝛼𝑇+(1−𝛼)𝑇′

 Compute the equilibrium distribution of the product

 mixture according to 𝑇 and 𝑝

Until |𝑇′−𝑇|<𝜏
