The Effect of Air Chamber Geometrical Design for Enhancing the Output Power of Oscillating Water Column Wave Energy Converter

Mamdouh Elmallah et al.

Summary: This study investigates the impact of geometry and design of an oscillating water column energy converter air chamber on airflow response. The goal is to optimize the air velocity entering the turbine by using different shapes of air chambers and varying cross sections. Modeling and numerical simulation are conducted using the ANSYS software. Results show that the air velocity significantly increases from 7.14 m/s in the rectangular air chamber to 10.4 m/s in the cylindrical air chamber, reaching a maximum of 14.2 m/s in the conical air chamber.

Performance analysis of a coast - OWC wave energy converter integrated system

Ao Gang et al.

Summary: This paper proposes a cylindrical dual-chamber oscillating water column wave energy converter semi-embedded in a coastline or breakwater. A theoretical model based on linear potential flow theory is developed to evaluate the power absorption performance of the integrated system in the finite water depth. The results show that the proposed system can improve the overall hydrodynamic efficiency.

Influences of wave resonance on hydrodynamic efficiency and loading of an OWC array under oblique waves

Xuanlie Zhao et al.

Summary: This study derived a semi-analytical solution from linear potential flow theory to investigate hydrodynamic characteristics of a rectangular oscillating water column array under oblique waves. The presence of along-shore sloshing resonance was found to decrease hydrodynamic efficiency and increase wave reflection, with the critical wavenumber being dependent on chamber length. Peak efficiency was observed at lower frequencies for larger incident wave angles, indicating that optimum coastal protection can be achieved by maximizing efficiency in the piston resonance frequency region.

A heaving system with two separated oscillating water column units for wave energy conversion

Chen Wang et al.

Summary: This paper presents a theoretical model based on the linear potential theory for two heaving oscillating water column (OWC) devices separated by a gap. The model includes relative motion and phase control between the devices and trapped water columns, and evaluates the hydrodynamic performance of the dual-OWC system. The study explores the effects of various parameters on the performance and proposes optimization strategies to enhance power extraction.

Long wave absorption by a dual purpose Helmholtz resonance OWC breakwater

Xuanlie Zhao et al.

Summary: This paper proposes a novel hybrid breakwater-WEC system for attenuating long waves. The system consists of a Helmholtz resonance oscillating water column (OWC) caisson array and a perforated wall. A semi-analytical model is developed to investigate wave interaction with the system, and the model is validated using numerical and experimental data. The hydrodynamic characteristics of the system and the influence of key parameters are studied. The results show that the system has advantages and superior performance in attenuating long waves.

Experimental investigation on the hydrodynamic performance of a multi-chamber OWC-breakwater

Xuanlie Zhao et al.

Summary: This paper investigated the hydrodynamic performance of single, dual, and triple-chamber OWC-breakwaters, with findings showing that the multi-chamber scheme improved wave power extraction characteristics and wave attenuation performance in longer waves. Wave steepness was found to be important for evaluating the performance of the multiple-chamber OWC-breakwater device.

Experimental investigation of a triple pontoon wave energy converter and breakwater hybrid system

Wei Peng et al.

Summary: A novel hybrid wave energy converter-floating breakwater system was developed in this study. Experimental research demonstrated that the integration of multiple energy-extracting pontoons could smooth out power output fluctuations, with pontoons having the same drafts showing higher energy conversion efficiency and pontoons with step change drafts being more effective in attenuating wave energy. Parameter analysis identified the balanced performance of the system as a WEC and a breakwater.
