Since CFD computations are expensive you can justify spending a little time on the tile-layout. This tile-layout also covers our wind farm with CFD results, but covers a greater part of the hill crest that has wind energy potential. After reorganizing the tiles it is possible to get the tile-layout shown on the next figure. By left-clicking a tile in the graphical window it is possible to drag it to a new position. As seen, two of the tiles are overlapping – that is allowed.Įventhough the suggested tiles will fulfill our basic need of covering our wind farm with CFD results, it may be possible to make slight improvements. km area and together they cover the WAsPdale turbines sites and the met.-station. Since we already know the layout of the wind farm we can simply click the button Cover sites and four red “tiles” are suggested.

In this window you can specify the area that you want to cover with CFD results. In order to do CFD calculations you must first specify CFD tiles.īy double-clicking on the CFD TA, a new window pops up.

This has been done on the picture below.Īs seen, the workspace now has a 'CFD' TA and all the other hierarchy members have been marked with red 'no entry' signs, meaning that you cannot do any calculation. One way of doing this is to right-click the IBZ TA and select Convert IBZ terrain analysis to CFD. In order to use the CFD model in your project you need to replace the IBZ TA with a CFD TA. In this example it has an IBZ label because the IBZ model has been used to calculate the wind climate. The vector map is placed as child to the TA, because the map is input to the flow model.Īnother change is the renaming of the “Wind atlas” hierarchy member to “Generalised wind climate” and that it has been given a TA label. This particular TA (WAsPdale, above figure) uses the flow model “IBZ”, which is the standard linearized model included in all WAsP distributions. The TA allows you to change which flow model you use in your WAsP project. The figure bellow gives an example of the workspace openned in WAsP 10 (left) and in WAsP 11 (right).Īs seen in the figure, one of the changes to the WAsP 11 workspace is that the vector map is now a child of the new hierarchy member the “Terrain analysis” (TA). When opening the WAsPdale workspace for the first time in WAsP 11 everything looks familiar, but a closer inspection reveals changes.

The CFD results used in this example can be downloaded for free from here. You can find information about WAsPdale in the WAsP 11 help file (“A step-by-step example”). WAsPdale (see figure below) is not a complex site and the use of CFD should normally not be considered, however, most WAsP users a familiar with the site and it is therefore used in this example. The starting point is a WAsP 10 workspace of WAsPdale.

This example shows you how to predict the power yield from a wind farm using WAsP CFD. We recommend that you view the demo videos (no audio): Each CFD tile costs one “Calculation credit” purchased from DTU via our web-shop. For large wind farms you can import as many CFD tiles as necessary. This is the procedure for making CFD simulations in WAsP.

You download the “result file” using the calculation manager and import it into WAsP.

On Cerebrum, the CFD model will automatically start the simulations and on completion save the tile results in a “result file”.

You uploaded the request file to Cerebrum using the “CFD Calculation Manager” tool in the WAsP Tools menu.

The tile coordinates and the project map is saved in a “request file” The figure below illustrates the process of acquiring CFD flow model results. In order to provide fast and high quality CFD computations, the actual CFD calculations are computed on the high-performance computer cluster “Cerebrum” operated by EMD international A/S. WAsP CFD works in much the same way as traditional WAsP and needs the same data for the calculations, e.g.
