Comparison of FAST.Farm and SOWFA

Hello Dr. Jason,

I am a new user of FAST.Farm and have run a few r-test cases available on GitHub. Now, I’m looking for published papers that use FAST.Farm to simulate wake steering in small wind farms with two or three turbines so that I can create the results and match them with the document. So far, I haven’t found any papers focusing on small wind farm wake steering with FAST.Farm, but I’ve come across several studies using SOWFA for this purpose. I’m interested in replicating the results from the paper " [Simulation comparison of wake mitigation control strategies for a two‐turbine case (wiley.com)]"(https://onlinelibrary.wiley.com/doi/epdf/10.1002/we.1810). I have a few questions:

  1. If I generate the test set-up given in the paper and run it in FAST.Farm, will the results of the turbine power production and DELs of the turbine components be the same as those obtained from SOWFA?
  2. What additional changes should be made in the FAST.Farm, so that I can get comparable results with SOWFA
  3. Do you have any relevant papers which I can run using FAST.Farm for 2-3 turbine cases so that it will help in my research as a benchmark case.

Dear @Ipsita.Mishra,

Here are my responses:

  1. We ran the exact case from the paper you cite with the curled wake formulation of FAST.Farm and published the results in the following paper: https://onlinelibrary.wiley.com/doi/full/10.1002/we.2785.
  2. Hopefully FAST.Farm will generate results close to SOWFA using DEFAULT wake parameters in FAST.Farm. But you most likely get improved results from FAST.Farm if you calibrate the wake parameters of FAST.Farm to the specific conditions (specific turbine, specific inflow) of the SOWFA simulations.
  3. Other useful papers involving calibration, validation, and application of FAST.Farm to wake steering can be found here: https://onlinelibrary.wiley.com/doi/full/10.1002/we.2756 and WESD - Load assessment of a wind farm considering negative and positive yaw misalignment for wake steering.

Best regards,

Thank You Dr. Jason for supporting me with relevant papers. I have gone through the first paper which you have mentioned in Sl.No.1. I am going through other papers too. I have certain observations and queries which I will post after I completely understanding the process adopted in each paper and how can I use it for my research.
