In calculating low Mach number flows one faces the stiffness problem in two different facets: • the applicable time steps become very small • the constants of the cancellation errors become very large (1/γ M 2 ). Usually the first point receives attention. Here we want to concentrate on the cancel
An experimental and theoretical investigation of the in#uence of a parallel shear #ow on the sound propagation in a circular duct is described. The theoretical model is based on a perturbation expansion at low Mach number of the modal equation for parallel shear #ows (Pridmore-Brown equation). In th
This paper concerns the finite element simulation of the diffraction of a time-harmonic acoustic wave in the presence of an arbitrary mean flow. Considering the equation for the perturbation of displacement (due to Galbrun), we derive a low-Mach number formulation of the problem which is proved to b
