Abstract:In the paper, the integrated structure of a dual cylindrical caisson embodying an OWC device is designed. The seaside hemi-toroidal column of the dual cylinder caisson is an air chamber for water column oscillation while the leeside hemitoroidal column of the dual cylinder is filled with sand for caisson stability. Experimental investigations were carried out on the performance of the OWC at different water depths, wave heights and wave periods, as well as on the layout of the caissons and the nozzle area ratio. Experimental results show that the water depth has significant effect on the wave energy conversion efficiency of dual cylindrical caisson breakwaters embodying an OWC. The new structure proposed as a breakwater or revetment structure especially arranged in a onethird convex arc has advantages in collecting more energy and creating a fine landscape environment.
