How does converge calculate the binary interaction coefficients for PR EOS on a gas simulation?

Lets say a gas is being injected in a nitrogen enviroment, where does that info come from to determine the mixtures critical properties?

Hello,

The binary interaction coefficients for all cubic EOS equations used in CONVERGE (RK, RKS, PR) are assumed to be zero.

CONVERGE allows you to use constant critical properties for all species or species-specific critical properties read from an additional input file.

Thanks,
