Abstract
In numerical simulation of subsonic and supersonic flows thermodynamic models built on the Boltzmann distribution are widely used. In these models the population distributions of the quantum states associated with each independent molecular degree of freedom follow a Boltzmann distribution and the major benefit deriving from this hypothesis is that the thermodynamics of a gas mixture can be described by a set of algebraic functions. However, for sufficiently high Mach numbers, the energy density of the flow field becomes considerably large and leads to more marked non-equilibrium effects; therefore, one should expect the Boltzmann distribution assumption to become less tenable.
