Mohapatra, S.C., Islam, H., Hallak, T.S. and Guedes Soares, C. (2022), “Solitary wave interaction with a floating pontoon based on Boussinesq model and CFD based simulations”, Journal of Marine Science and Engineering, Vol. 10, 1251.
A mathematical model of solitary wave interaction with a pontoon-type rigid floating structure over a flat bottomis formulatedbased onBoussinesq-typeequations under weakly nonlinear dispersive waves. Based on the higher-orderBoussinesqequations, the solitary wave equationis derivedand a semi-analytical solution is obtainedusingthe perturbation technique. On the other hand, brief descriptions of the application of wave2Foam andOceanWave3Don the aforementioned problemis presented. The analytical solitary wave profiles in the outer regionare comparedwith Computational Fluid Dynamics (CFD) andOceanWave3D model simulations in different cases. The comparison shows a good level of agreement between analytical, wave2Foam, andOceanWave3D. In addition, based on the wave2Foam andcoupled OceanWave3Dmodel, the horizontal, vertical wave forces, and thepressuredistributions around the pontoonare analysed. Further, the effect ofthe Ursellnumber, pontoon length, and water depth on the solitary wave profilesare analysedbased on the analytical solution. The paper validates each of the three models and performs intercomparison among them to assess their fidelity and computational burden.
