Abstract
This paper studies the applicability of various versions of the regularized 13-moment system (R13) as applied to the problem of the shock wave structure in a monatomic Maxwell gas in a wide range of Mach numbers (1.0<M<8.0). Over time, several versions of the R13 equations were presented, which differ in non-linear contributions for high-order moments. The challenge of this study is to determine the range of applicability of each variant of the moment equations as applied to non-equilibrium supersonic flows, depending on the Mach number and local Knudsen number. Numerical results obtained for the R13 system are compared to DSMC data computed by the SMILE++ software system.
