Noise influenced by multiphase flows becomes an increasingly important issue.
Numerical simulations can help for a better understanding of sound behavior within
heterogeneous media. In this work, we present a coupled approach for computing incompressible
heterogeneous fluids with sound wave propagation. The linearized Eulerian
equations are used for the transport of the sound waves. We investigate the propagation
of the waves in the presence of a fluid/fluid interface and we verify the introduced approach.
The method is also tested with an inclined interface, where different refraction
angles are investigated. The refraction as well as the reflection of sound waves can be
predicted with errors of less than one percent.
