As explained in Chapter 4.8 of the report, the thermo.compressibleGas dictionary contains the last version of the newly generated thermophysical coefficients for hydrogen, oxygen, and nitrogen molecules. These coefficients are required for the implemented nasa9Poly thermodynamic model and nasaPoly transport model. These coefficients can be used from the boiling points of these species up to 6000 K.
However, in the case of using these two thermophysical models for other temperature intervals or even other species, you can use the original NASA-9 coefficients for the nasa9Poly thermodynamic model and the original NASA-7 coefficients for the nasaPoly transport model.
In order to use the thermo.compressibleGas dictionary, you can download the file and move it to the constant folder of your OpenFOAM case and add the below code line into your thermophysicalProperties file.
foamChemistryThermoFile "$FOAM_CASE/constant/thermo.compressibleGas";
In the same file, you should also change the thermodynamic and transport models into nasa9Poly and nasaPoly.
