About the axially symmetric flows of the viscous heat conducting gas

It was obtained some truncated systems of the equations for the axially symmetric flows of the viscous heat conducting gas with the help of the Newton polyhedra. The self-similar solution of a truncated system is considered with the appropriate boundary conditions. This solution describes the asymptotic behaviour of the gas flow at infinity in the conic diffuser by the low Mach and Reynolds numbers. The approximate analytical solution was obtained for the case of the diffusers of the small angles.
