| Abstract: | The artificial viscosity method for three—dimensional unsteady gas flow is developed. The stability of finite difference scheme
in this case is investigated. The necessary and sufficient conditions for the stability are obtained; these conditions formally
agree with the two-dimensional result in Rusanov's paper. |
