Numerical Modeling of Gas Flows in the Transition between Rarefied and Continuum Regimes
- In this paper we derive fluid dynamic equations byperforming asymptotic analysis for the generalized Boltzmann equationfor polyatomic gases. In particular, we consider the steady state,one-dimensional Boltzmann equation with one additional internal energyand different relaxation times. Moreover, we present a new approachto define coupling procedures for the Boltzmann equation and Navier-Stokesequations based on the 14-moments expansion of Levermore. These coupledmodels are validated by numerical simulations.
