dc.description.abstractNoise 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.
