Minimal strutcural file requirements
Good afternoon,
Thank you for sharing and developing QBlade, it is a very practical and useful tool.
I am encountering issues with understanding how the structural modeling files work. I have created a H-type VAWT turbine in the software and I am able to run simulations without a structural model.
In the scope of my research, I do not want to consider any structural properties of the turbine, I only need the aerodynamics. However, I would like to implement pressure sensors on the blades as well as active blade pitching controlled by a python script. From my understanding, I need to load some structural model file to be able to include those.
I am having a hard time understanding what minimal information is needed within the structural modeling file and the blade property files.
I do not have a CAD model of the turbine, is it possible to proceed without one? I do not need a very accurate representation of my turbine.
Thank you very much for your time and support.
Hi,
setting up a complete structural model of a wind turbine can be a daunting task, requiring a good understanding of the structural design of several turbine components. The required data, and how such a model is setup in general is detailed in the documentation here. The learing curve can be quite steep to setup everything correctly and consistently.
If you prefer not to model the turbine structurally you could impose dynamic pitching motion either through Simulation Input Files, or by running QBlade in the Software in Loop (SIL) Interface, from where you can call the function dll_SetControlVars(), to dynamically change the pitch.
A “pressure sensor” is not available in QBlade, however you could compute the dynamic pressure from velocity signals measured at the blade.
BR,
David
