Hydrodynamic performance of the dual-chamber oscillating water column device placed over the undulated sea bed

The present study analyzed the efficiency of the dual-chamber oscillating water column device placed over the undulated bottom. The efficiency of the device is studied for various shape parameters such as chamber lengths, the draft of the lip wall of the device, turbine damping coefficients, and rip...
