In this project, we applied the Forchheimer flow model in Computational Fluid Dynamics (CFD) simulation to characterize the flow through an orifice used as a quadratic Power Takeoff (PTO) for the Halona oscillating water column (OWC) wave energy convertor (WEC) in the experiments. This proposed method has been successfully utilized for a fixed omnidirectional spar buoy WEC in regular waves. The objective of this project was to extend the application of this method to a floating WEC. This resource contains the final project report and the modeling data associated with each figure contained in the final project report. The file names are consistent with the figure numbering in the final report. There is a README included in each ZIP folder if the file name is not self-explained. Additional description and explanation for each figure can be found in the report.
