Abstract

A finite element method for acoustic wave propagation is established, taking into account the influence of a time-independent inhomogeneous flow on the acoustic waves. The simulation scheme is verified for homogeneous flow and validated with geometrical acoustics for inhomogeneous flow profiles. As an application, the wave propagation within ultrasound flow meters for liquids is computed for different flow profiles
