I am testing a horizontal wind turbine inside the test section of a wind tunnel. If I have a blockage ratio of about 19 percent, is it acceptable or not? If it is unacceptable, how do I calculate the correction factor necessary to calculate the correct power coefficient value, with references, please?
Regarding the simulation, I am using the ANSYS program, I made the same dimensions of the test section for the stationary domain and under the same conditions as wind tunnel tests. Should I use the correction factor on the results or only on the experimental results?
many thanks
