All over the world, companies are trying to invent deep sea energy production devices. This ranges from reimagining known devices such as making floating wind turbines and solar cells to completely new technology such as wave energy converters (WECs).

With every new kind of devices placed at sea, there is a fundamental need to understand the exact interactions between the ocean and the object placed in it. This need is even bigger for a WEC, as it produces energy from its interaction with the waves. Many WEC technologies are tested through prototype testing, without a thorough analysis of the physical phenomena that describe how they work.

This project focuses on a new WEC technique that uses the pressure from the circular motion of the waves to move the device. This method has not been analyzed through CFD before. This project will setup a model to describe the WEC and investigate the theoretical efficiency of the device. The focus will be on understanding the specific phenomena that drives the energy production.

The company Crestwing, which has designed a WEC that uses this principle, will be making their data available for comparisons and analysis.

Technical University of Denmark

For almost two centuries DTU, Technical University of Denmark, has been dedicated to fulfilling the vision of H.C. Ørsted – the father of electromagnetism – who founded the university in 1829 to develop and create value using the natural sciences and the technical sciences to benefit society.


Today, DTU is ranked as one of the foremost technical universities in Europe, continues to set new records in the number of publications, and persistently increases and develops our partnerships with industry, and assignments accomplished by DTU’s public sector consultancy.
