Default Thermophyiscal Models for Compressible Combustion

Does anyone have any information regarding the variety of Thermophysical models used in reactingFoam and dieselFoam (the PaSR model solvers)? Specifically, how is the compressibility dealt with? I see that the default practice is to use an enthalpy-compressibility formulation (hPsiMixtureThermo). I don't know how this model works, so if anyone can help me here, that would be much appreciated.

Thermophysical properties are set in the simulations by the line below. I am unsure also of what "gasThermoPhysics" refers to. <> didn't really help.

thermoType hsPsiMixtureThermo<reactingMixture<gasThermoPhysic s>>;

Ideally, I want an ideal gas equation of state governing the compressibility in my simulations. Is this possible with reactingFoam/dieselFoam?

Many thanks in advance
