SOLITARY WAVE FORCES ON AN ARRAY OF CLOSELY-SPACED CIRCULAR CYLINDERS

A series of hydrodynamic experiments were conducted to investigate the solitary wave interaction with a slotted barrier model and a single cylinder in a wave flume. Water particle velocities under solitary wave were measured and compared with theoretical values. Wave forces were measured and hydrodynamic coefficients were investigated and compared; Results showed that, for multiple cylinders, drag coefficients decreased as incident wave height increased; inertia coefficients were much scattered and not given in this report. The drag coefficient values for a single cylinder showed different tendency with those of the slotted barrier model (multiple cylinders). These two situations were not comparable because of the blockage effect.
