Chapman-Enskog expansion: Boltzmann equation and Navier-Stokes equations

  • Tai-Ping Liu

摘要

The validity of the Chapman-Enskog expansion for the derivation of Navier-Stokes equations from the Boltzmann equation is assessed through examining their solutions. This is considered also by comparing two versions of the derivation.
