摘要:

Among the various numerical schemes developed since the ’80s for the computation of the compressible Euler equations, the vast majority produce in certain cases spurious pressure glitches at sonic points. This flaw is particularly visible in the computation of transonic expansions and leads lo unphysical “expansion shocks” when the flow undergoes rapid change of direction.
