Abstract:
The monotonicity and stability of a finite difference scheme with respect to initial data in the supremum norm are analyzed as applied to the polytropic gas equations written in terms of Riemann invariants for subsonic flows with $1<\gamma<3$. Conditions on the initial and boundary data are obtained under which subsonic flows with no shock waves develop in the medium. The theoretical conclusions are supported by numerical results.
Key words:
numerical solution of gasdynamic problems, Riemann invariants for polytropic gas, finite difference method, stability and monotonicity of difference schemes.
