Absorption of water waves in a two-dimensional numerical flume

Summary. In this work the absorption of water waves in a nu merical wave flume is discussed in terms of performance and robustness. A general f ormulation for the analysis of fluidstructure interaction problems using the Particle F inite Element Method (PFEM) 1 is employed to simulate a numerical wave flume. The implementation of a wave dissipative zone changing the fluid viscosity properties is tested with the g oal of absorbing waves reflected by a vertical wall. The accuracy of this method is analyzed testi ng a set of viscosity distribution inside the dissipative zone using a prototype scale numerical wave flume.
