Using the DRAGFO subroutine to model Tidal Energy Converters in Telemac-2D
Abstract
In the past few years the research on Tidal Energy Converters (TECs), or Tidal Turbines, has increased (see for example the work done at the EMEC 1). As such a demand arose to assess the impact of potential large industrial TEC farms. This demand has also been growing in the Telemac User community, see for example Haverson et al. [2] or de Paula Kirinus et al. [1], but no clear methodology has been defined within the Telemac-Mascaret system. To model the hydrodynamic effects of TEC over large areas, two approaches are possible. One can either use the actuator disk method, where the influence of a TEC is modelled through a head drop [6], or it is possible to model the drag force induced by a TEC opposing the flow (this can be thought of as being similar to increasing the bed friction). This second approach has been successfully applied by EDF in Telemac-2D through the PerAWaT project 2 and its recommended implementation in Telemac-2D will be described in this article. Furthermore its implementation will be illustrated by reproducing the experiment conducted by the University of Manchester within the PerAWaT project [7].
