SHORT NOTE: Validation of CFD models for tsunami simulation. TANDEM Project

Abstract

Into the frame of the TANDEM project (Tsunamis in the Atlantic and the English ChaNnel: Definition of the Effects through numerical Modeling) a first step of the study aims for Principia to qualify different 3D CFD (Computational Fluid Dynamics) models for the simulation of tsunamis. The EOLE code solves a 3D bi-fluid flow on multi-structures meshes coupled with a free surface tracking VOF model, whereas the EOLENS code is based on an interface capturing method using unstructured meshes. This paper presents some simulations / measurements comparisons for academic test cases of wave propagation and run-up. On the whole, the results are satisfactory showing the high potential of both codes to simulate tsunamis impact.
