The purpose of this work is to evaluate the thermophysical properties of combustion gases of the gas turbine engine using the Soave‐Redlich‐Kwong equation of state and to compare the results with those obtained from the virial equation of state and the experimental values obtained from experiment and the generalized charts. The properties which have been considered in this work were, density, specific heat at constant pressure, enthalpy, entropy, viscosity and thermal conductivity. The temperature range was (200–2600 K) theoretically, while the pressure range was (3–12 atmospheres). The Soave‐Redlich‐Kwong (SRK) equation of state generally predicted better values for thermophysical properties than those predicted by the virial equation of state. A computer program, to evaluate the departure of thermophysical properties using virial and SRK equations of state, was used.
