2D Simulation of a Free-Floating Body Motions under Linear Waves Using a Smoothed Particle Hydrodynamics scheme abstract
In this study, a modified weakly compressible smoothed particle hydrodynamics (WCSPH) scheme is used for simulating the rigid motions of a freely floating body with 3 degrees of freedom (heave, sway, and roll). In the modified WCSPH scheme, a new equation for simulation of wave-structure interaction and calculating hydrodynamic forces is used. To evaluate the efficiency of the new proposed scheme, a numerical wave flume with a flap-type wave maker has been simulated and the results are compared with the experimental data. The results obtained from the new SPH scheme reveal that the proposed scheme is more accurate and reliable than the classic SPH scheme in estimation of the rigid body motions.
