About the Steady Flow of the Viscous Heat Conducting Gas in the Planar Diffuser.

Abstract:

It is considered the asymptotic behaviour of the solution to the whole system of Navier-Stokes equations for the problem of the viscous heat conducting gas steady flow in the plane diffuser with the help of the power geometry. This problem was investigated in the one of previous preprints of the author with the use of the truncated system of the equations corresponding to small Reynolds and large Euler numbers. In this case was obtained the approximate analytic solution in the form of the portions of power series for the small diffuser angles. This solution is corrected here with regard to next terms of the expansion.
