Abstract
A finite element method for acoustic wave propagation based on a modif ied wave equation is established, taking into account the influence of a time-independent inhomogeneous flow on the acoustic waves. The simu lation scheme is verified for homogeneous flow validated with geometri cal acoustics for inhomogeneous flow profiles and compared with previo usly developed techniques, such as Helmholtz-Kirchhoff integral and ra y tracing methods [4, 13]. As applications, an ultrasound flowmeter an d a sound protection shield are studied for different flow profiles.
