Numerical and Experimental Modelling of Wave Energy Converters (2020)

  • Description:

    The work to develop wave energy converters (WECs) typically involves intensive laboratory model testing in wave tanks and/or flumes at the earlier stages, and intensive testing and monitoring of prototypes in real seas at later stages. During the various development steps numerical modeling offers possibilities of investigation of larger parameter ranges than allowable in experimental modeling, and is therefore an essential tool for optimization. When working with optimization of the power performance of a wave energy device, the control hereof, via the power take-off system is of paramount importance.The Wave Energy Research Group at Aalborg University (AAU), Department of Civil Engineering offers a PhD course running over two consecutive weeks.
    The course is split into 3 modules:
    • General introduction, experimental modeling and testing
    • Numerical modeling
    • WEC control and experimental implementation

  • General introduction, experimental modeling and testing:
    The objective of the first module of the course is to introduce and apply wave analysis theory, laboratory measuring techniques, prototype monitoring and control. The module will include class room lectures, laboratory exercises in the wave tanks/flumes and a visit to a wave energy test installation in real sea.
    This module will include the following subjects:
    • Wave analysis
    • Measuring techniques for waves, loadings and power take-off
    • Analysis of laboratory and real sea data for performance evaluation

  • Numerical modeling:
    The objective of the second module of the course is to introduce and getting experience with running numerical models of WECs including modeling of PTO and its control. The module will include class room lectures and exercises.
    This module will include the following subjects:
    • The state of the art of numerical modeling for WECs
    • Limitations of these techniques and the existence of other numerical approaches for hydrodynamic modeling
    • Development of a numerical wave to wire model

  • WEC control and experimental implementation:
    The objective of the third module of the course is to go through the basics of control of WECs (based on wave activated bodies) and work its way through to more complex control approaches. The module will include class room lectures, laboratory exercises in the wave tanks/flumes
    This module will include the following subjects:
    • Model Identification strategy for WECs
    • Control of wave energy devices
    • Implementation of WEC control methods in experimental testing

The course is arranged through the Doctoral School of Engineering and Science at Aalborg University.

For PhD students registered at any university, participation in the course itself is free. However, a fee will be charged to cover expenses for lunches, coffee, transportation, etc. For non-PhD students, an additional registration fee will also be charged. The fees will be charged after the registration deadline is passed and registrants have got the confirmation of participation.

The course is of relevance to PhD students and others with interests in development of wave energy devices.

Prerequisites: 

  • Degree in Engineering

    Basic knowledge of Matlab or any other programming language

    Some knowledge of fluid mechanics and wave kinematics, dynamic structures/mechanical systems, potential flow (linear wave) theory.

    Fourier transform and stochastic processes, as well as good skills in mathematical analysis.

Important information concerning PhD courses 
We have over some time experienced problems with no-show for both
project and general courses. It has now reached a point where we are forced to
take action. Therefore, the Doctoral School has decided to introduce a no-show
fee of DKK 5,000 for each course where the student does not show up.
Cancellations are accepted no later than 2 weeks before start of the course.
Registered illness is of course an acceptable reason for not showing up on
those days. Furthermore, all courses open for registration approximately three
months before start. This can hopefully also provide new students a chance to
register for courses during the year. We look forward to your registrations
