we are using the NREL 5MW Reference Turbine in our LES code for simulating the flow behind wind turbines and within wind farms.
The LES model is an open source code (PALM → palm.muk.uni-hannover.de ) and we added three different turbine parameterizations (actuator disk, acutator line and enhanced actuator disk with rotation) to this code which are based on the NREL reference turbine data.
So far, our additional code is in a separate user interface and only used by us. In the future, however, we plan to integrate our turbine parameterization as a module to the standard code so that other users can use it, as well.
We have created ascii tables of the turbine data in a specific format which are read in when the simulation is started. When adding our code to the standard code we would also have to upload these tables to the code repository.
My questions: Are we allowed to do this? Do we need permission by the authors of the NREL reference turbine? Do we need to add some acknowledgement, copyright, … in the tables and in the code module?
