STUDY ON NUMERICAL SIMULATION OF TSUNAMI BY USING 2D-3D HYBRID MODEL

Abstract

 In this study, the two-dimensional and three-dimensional hybrid model by the solver “shallowInterFoam” that works on the OpenFOAM platform, was verified the relevance of its analysis in comparison with the results of hydraulic model experiments on the flow around the breakwater. Hybrid model calculation results were consistent with the hydraulic model experiment data and three-dimensional model calculation results. Furthermore, the practical improvement was achieved by improving the coupling method between the 2D model and the 3D model, such as enabling the application of unstructured grids.
