Self-similar flows of the Abel - Noble gas in a planar diffuser

Laminar flow within a planar diffuser of viscous gas, obeyed the Abel - Noble equation of state is considered. System of the Navier - Stokes partial differential equations are reduced to the system of ordinary differential equations. In the case of flow within a slender channel at low subsonic velocity the problem is solved analytically. In general case the system is solved numerically in a wide range of the defining parameters variation.
