Numerical Analysis of Two-Body Floating Attenuator WEC (Waveberg)

In curation License 

This TEAMER RFTS 9 award was used to develop a numerical model of the Waveberg floating attenuator wave energy converter (WEC) using the Wave Energy Converter-Simulator (WEC-Sim). The Waveberg is designed to generate power in the smaller waves (for wave heights of 1 - 2 meters) predominant in the world.

The project involved developing a WEC-Sim model of the Waveberg 1:25 model tested in the wave flume at Stevens Institute Davidson Laboratory. The Waveberg uses a piston pump as the PTO; the back pressure on the pump is the key operating variable. The model did not achieve the scaled pressure of 32 PSi; tests were done at 3.5 up to 14 PSI. The runs used to calibrate the simulation model were done at 3.5 and 4 PSI.

Analysis of these tests on a new 1:25 scale model supports a valuable understanding of Waveberg?s dynamics in real wave conditions. The tank testing included an initial characterization of dynamics using free decay and response amplitude operator (RAO) tests. More advanced testing was also carried out to characterize power output and test novel improvements including hydrofoils to increase lift.

The files here include all files needed to run the model and reproduce the charts in the Post-Access report (linked below). There are 3 Excel files with results from the model for 4, 8 and 32 PSI. You will need WEC-Sim as well as Matlab to run the model.
