520 3 |a In order to calculate the wave loads on the small and medium scale bars of composite structures accurately, not only the action of incident wave but also the wave diffraction caused by near large-scale structure and the effect of radiation on wave load of small scale bars should be considered. In this paper, based on the VOF method, the three-dimensional wave numerical flume of the wave acting on the composite structure is constructed in Fluent. The incident wave force, diffraction wave force and total force acting on the composite structure are obtained by numerical calculation. Compared with the results obtained by using the Morison formula alone, the effectiveness of the wave loads calculated by the model is verified. The results show that under certain wave conditions, the wave diffraction caused by large-scale structures can not be ignored. In addition, the influence of the incident wave number, the diameter of the pile and the position of the pile on the wave load of the small-scale pile is also studied. The results can provide a scientific reference for the accurate calculation of wave loads on small-scale piles in marine engineering with composite structures.
