Task 10 - Wave Energy Conversion Modelling Verification and Validation

MAJOR ACHIEVEMENTS
Task 10 was initiated in late 2016 aiming to verify and validate numerical models used in the design of wave energy converters and power production calculations, with the following long-term goals:

  1. To assess the accuracy and establish confidence in the use of numerical models;
     
  2. To validate existing computational modelling tools;
     
  3. To identify uncertainties related to simulation methodologies
     
  4. To define future research and develop methods of verifying and validating the different types of numerical models.


Experience from similar offshore wind validation/verification projects (OC3-OC5 conducted within the International Energy Agency Wind Task 30) showed that a simple test case would help the initial cooperation to present results in a comparable way.

Phase I of this task was then focused on a simple, surface piercing spherical body. Overall good agreement was found among codes with different fidelity levels.

A second meeting was organized in Amsterdam, at 13-14 March 2017, with 13 participants and other 10 experts via webinar. This meeting was hosted by the Danish delegate, Kim Nielsen (Ramboll) and sponsored by the OES, with the following agenda:

  1. Review the methodology used and develop methodology further;
  2. Propose a generic WEC example and next simulation examples;
  3. Discuss existing experimental data sets for validation of numerical results;
  4. Select best suited experimental data set for initial test case;
  5. Agree on publication strategy.

Further, 3 webinars on 01-07-2017, 28-02-2017 and 19-09-2017 were organized during the year.
