Abstract: Calculations 2D-dimentional test gas dynamics problems by a new, net method of adaptive artificial viscosity (AAV), in detail described in [1] and [2], generalized in [3] on a case of two and three measurements are resulted. In Cartesian coordinates in Eulerian variables in a rectangular and step areas the equations are considered.
The equations become isolated the equation of a condition ideal gas. Test problems are taken from [4]–[6]. Comparison of the decision of these problems by method AAV and by other methods published in clauses [4]–[6] is spent.

Keywords: 2D-dimentional gas dynamics problems, method of adaptive artificial viscosity.
