Study of Wave Structure Interaction Based on the SPH and FCBI Algorithm

Abstract:

Abstract. Based on the theory of numerical calculation, the SPH algorithm and FCBI algorithm were used to establish the corresponding water body model, and to calculate the fluctuations of the water by controlling water boundary parameters. In addition, the dam model was established based on the finite element method, and correspondingly two-way coupling with these two fluid boundary in order to examine the effect of fluid structure interaction by these two algorithms. The calculated results show that: the wave shape generated by this two algorithms is broadly consistent, however, the results obtained by the SPH algorithm can more completely show details; In addition, wave structure interaction effect calculated by SPH algorithm is stronger than the ones derived from FCBI algorithm, with the non-linear characteristic of the wave increase, the difference of the two algorithms is increasing. The the wave force calculated by the traditional linear wave theory needs some correction.
