Abstract: In work the method of adaptive artificial viscosity (AAV) [1, 2] in the appendix to problems of gas dynamics in cylindrical, spherical and Cartesian coordinates is considered. The new way of a choice of the artificial viscosity, leading weak (on three intervals) is offered smoothing of shock waves and accurate suppression oscillation of the decisions. Results of test calculations are resulted.

Keywords: difference schemes, adaptive artificial viscosity, systems of gas dynamics.
