The Asymptotic Behavior оf the Steady Viscous Heat Conducting Gas Flow in the Planar Diffuser

The various truncated systems of the equations were obtained for the plane steady flows of the viscous compressible heat conducting fluid by the means of the Newton polyhedra. The automodelling solution of a certain such system is considered in the present preprint. This solution describes the asymptotic behavior of the flow at infinity in the plane diffuser provided that the Reynolds number is small and the Euler number is large. The approximate analytical solution was obtained for the case of the diffuser of the small angles.
