Experiments and computations of wave-induced oscillations of submerged horizontal plates

Wave-induced oscillations of submerged horizontal plates are studied by conducting laboratory experiments and developing theoretical computational models. These models include a linear solver based on the Green-function method, nonlinear model Green–Naghdi wave equations, fluid dynamics. The plate oscillates in vertical direction due to oscillatory loads. Oscillations controlled use spring-damper system. Laboratory measurements provide quantitative information (i) how vary with conditions, characteristics, control system (ii) different using levels assumptions predict wave-induced oscillations. Particular attention is given energy-production applications oscillating plate, discussion provided oscillation height velocity its initial submergence depth, stiffness attached spring, strength viscous damper. It found that varies almost linearly height, but nonlinearly period, depth damping, spring stiffness. Overall, it nonlinearity plays an important role this problem, while effect viscosity negligible.
