 Effect of relative chamber width on energy conversion and mechanical characteristics of the offshore OWC device: A numerical studyMing Qu, Dingyong Yu, Yufeng Li and Zhiyang Gao Energy, 2023, vol. 275, issue C Abstract: In order to investigate the effect of the relative width D/D0 on the energy conversion and mechanical characteristics of offshore OWC device, the variation of pressure, air flow and wave force on structure of the offshore OWC chambers with length B = 0.40, 0.45, 0.50 m and D/D0 = 1, 4/5, 2/3, 1/2 were studied under the wave condition of relative wave height H/h = 0.2, incident wave period T = 1.3, 1.4, 1.5, 1.6, 1.7, 1.8, 1.9, 2.0, 2.1s by numerical simulation. Based on the simulation results, the effects of D/D0 on the parameters of energy conversion, mechanical and hydrodynamic characteristics of the offshore OWC chamber are analyzed. The results show that in most cases, the chambers with D/D0 < 1 have better or similar comprehensive energy conversion-force effect and better force process than the one with D/D0 = 1. The combined effect of the chamber with D/D0 = 4/5 is the best, the wave force on it could be 0.7 times and the energy conversion efficiency could be 1.1 times as compared with that with D/D0 = 1. The research results can provide reference for the design of OWC device.
