摘要
A new type of floating platform with integrated offshore wave energy conversion device is proposed,by integrating a damping pool type floating platform with an OWC wave energy device,the front wall of the OWC chamber is fixed or connected to the chamber by a top hinge. Based on the three-dimensional potential flow theory,the capture width ratios of the air chamber and the pendulum front wall under different wave periods,different platform drafts and different air chamber sizes are studied. Results show that different platform drafts and different chamber sizes affect the capture width ratio of the chamber by influencing the resonance periods of the platform and the chamber,and under the condition of larger platform drafts and smaller chamber front wall drafts,the problem of wave slaming at the top of the air chamber and the front wall will occur. For a given wave environment,there exit an optimal hinge rotational damping,which makes the capture width ratio of the swing plate highest. For a given hinge rotational damping,the capture width ratio of the pendulum gradually decreases with increasing wave period,at lower wave periods and platform resonance periods,the pendulum front wall structure has a larger chamber capture width ratio than the fixed front wall. ? 2024 Science Press.
