A Continuum Description of Rarefied Gas Dynamics (I)--- Derivation From Kinetic Theory
Xinzhong Chen, Hongling Rao, Edward A. Spiegel
We describe an asymptotic procedure for deriving continuum equations from the kinetic theory of a simple gas. As in the works of Hilbert, of Chapman and of Enskog, we expand in the…
