Calculations of two-dimensional test problems by the method of adaptive viscosity

The paper is concerned with calculations of two-dimensional test gas dynamic problems through a new artificial viscosity grid method. A detailed account of this method is given in 1, 2]; it was extended in 3] to two and three dimensions. The equations are considered in a rectangle and in step-shaped regions using Cartesian coordinates and Euler variables, and they are closed by the gas law of ideal polytropic gas. Test problems are taken from 4–6]. A comparison of the solution of these problems as obtained by the AAV method and other methods put forward in 4–6] is made.
