NREL 5-MW reference turbine - CP, CQ, CT Coefficients

Dear Rannam,

I have never published the complete Cp, Cq, and Ct tables of the NREL 5-MW turbine. Back in 2004 (!), I used WT_Perf v3.00 to generate the Cp surface of the NREL 5-MW baseline wind turbine. The WT_Perf input files I used for this and the results plotted in a spreadsheet are attached. At that time, I also ran a similar analysis with FAST, the results of which are also attached. I thought that the comparison between FAST and WT_Perf was reasonable, considering that the FAST model has numerous additional features, such as dynamics and tower and blade flexibility.

It should be fairly straightforward to modify the WT_Perf primary input file (.wtp) and rerun WT_Perf so that the Cq and Ct values are also computed. See the parametric analysis section at the end of the input file. Please note that WT_Perf v3.10 was released since I generated these results. WT_Perf v3.10 is the version currently available on the website. You will have to update the attached input file slightly so that it is compatible with WT_Perf v3.10.

Please post the results here.

I hope that helps.

Best regards,
