Performance of an U-Shaped Oscillating Water Column Wave Energy Converter Device under Oblique Incident Waves
The present study deals with the performance of an U-shaped oscillating water column device under the action of oblique incident waves. To solve the associated boundary value problem, the dual boundary element method (DBEM) is used. Various physical parameters associated with the U-shaped OWC device...
