Abstract

• Development of a model for acoustic propagation suitable for incompressible multiphase fluids. • Model discretization with an entropy-stable DGSEM formulation. • Quantification of modeling errors due to interface thickness in acoustic transmission. • Validation of acoustic transmission and refraction according to Snell’s law. • Three-dimensional spherical wave propagation across a flat air–water interface.
