Recognizing that R/M is also known as the specific gas constant, [R.sub.s], then the ideal gas law can simply be expressed as P = [[rho].sub.0][R.sub.s]T.
[R.sub.unburned] = 287 J/(kg * K) is the specific gas constant of unburned gas mixture.
In computational fluid dynamics software, gas is considered ideal and has a fixed composition with a specific gas constant. The specific gas constant can be deduced from experiments in which the gas is collected in a fixed volume apparatus and the gas pressure is measured.
