摘要: Numerical flux functions for solving the Euler equations using exact and/or approximate solutions of Riemann problem gasdynamics are discussed. Under certain restrictive conditions, schemes these produce systems which can exhibit a single degree freedom. In some instances, represented by this freedom unstable to perturbations. This local instability seriously degrade temporal convergence numerical schemes. point is demonstrated example.
