Abstract

IN THIS STUDY, THE DYNAMIC MOTIONS OF A RECTANGULAR CHAIN-MOORED FLOATING BREAKWATER WITH THREE DEGREES OF FREEDOM (HEAVE, SWAY, AND ROLL MOTIONS) ARE SIMULATED USING A WEAKLY-COMPRESSIBLE SMOOTHED PARTICLE HYDRODYNAMIC (WCSPH) SCHEME. A REGULAR WAVE IS SIMULATED USING A PISTON TYPE WAVE MAKER INSIDE A NUMERICAL WAVE FLUME. THEN, A RECTANGULAR MOORED FLOATING BREAKWATER IS PLACED INSIDE THE DEVELOPED NUMERICAL WAVE FLUME AND THE DYNAMIC MOTIONS OF THE STRUCTURE ARE RECORDED. IN THE DEVELOPED NUMERICAL SCHEME, THE WAVE-STRUCTURE AND MOORING-STRUCTURE INTERACTIONS ARE EVALUATED BY SOLVING NEW SPH-BASED EQUATIONS. IN ADDITION, THE MOORING SYSTEM IS SIMULATED BY THE SPH PARTICLES. COMPARING THE OBTAINED RESULTS FROM THE DEVELOPED SPH SCHEME WITH THE EXPERIMENTAL DATA REVEALS THAT THE MODIFIED SMOOTHEDPARTICLE HYDRODYNAMIC SCHEME IS ABLE TO SIMULATE THE DYNAMIC MOTIONS OF A CHAIN-MOORED FLOATING BREAKWATER WITH A REASONABLE ACCURACY.
