Recovery of Transport Coefficients in Navier-Stokes Equations from Modeled Boltzmann Equation

摘要

It has been shown that the complete set of unsteady compressible Navier-Stokes equations can be derived from an improved BGK modeled Boltzmann equation. Thus formulated, the first coefficient of viscosity and the thermal conductivity are recovered correctly, together with the specific heat ratio for diatomic gases.
