Abstract: Abstract Accurate numerical simulations of wave phenomena are important in many fields, for example in electro magnetics, seismics and acoustics. We are interested in aeroacoustic problems with a non-vanishing mean flow. The governing equations are the Euler equations. In a typical aeroacoustic situation the solution consists of a slowly varying mean flow with an added small amplitude acoustic wave.
