Solitary Wave Interaction with a Floating Pontoon Based on Boussinesq Model and CFD-Based Simulations

A mathematical model of solitary wave interaction with a pontoon-type rigid floating structure over flat bottom is formulated based on Boussinesq-type equations under weakly nonlinear dispersive waves. Based the higher-order Boussinesq equations, equation derived, and semi-analytical solution obtained using perturbation technique. On other hand, brief descriptions application wave2Foam OceanWave3D aforementioned problem are presented. The analytical profiles in outer region compared Computational Fluid Dynamics (CFD) OceanWave 3D simulations different cases. comparison shows good level agreement between analytical, wave2Foam, OceanWave3D. In addition, coupled model, horizontal, vertical forces, pressure distributions around pontoon analysed. Further, effect Ursell number, length, water depth analysed solution. paper validates each three models performs intercomparison among them to assess their fidelity computational burden.
