In order to gain a deeper understanding of the influence of caisson structures on wave propagation and reflection,the numerical simulation was employed to investigate the interaction between waves and perforated caissons.To explore the optimal open hole location for wave attenuation effects,a numerical wave flume based SPH method was established to analyze the effects of three different open hole locations on the reflection coefficient Kr,wave surface elevation variation,vorticity field,and flow field.The influence of different open hole locations on wave attenuation effects was summarized.The study reveals that the caisson has the smallest reflection coefficient Kr and the least variation in wave surface elevation outside the caisson when the top of the opening is submerged 0.08 m underwater.Moreover,the open hole location in the caisson exhibits the highest total vorticity consumption and the flow field variation is 1-2 times higher than the other two open hole locations,resulting in the calmest wave surface in the caissons and the best wave attenuation effects.The obtained conclusions provide certain guiding significance for the study of wave attenuation effects in practical engineering applications of perforated caissons.
