[@angusgrieve]

You are a saint! this may have just saved my dissertation

[@ozcanatlam2057]

That is very usefull about wind turbine aerodynamic effects on the performance

[@rightalex7]

Thanks allot 👍

Please can you make the same demonstration for a VAWT?

I have a question, why you dont input the swept or wide area of your blade in your lift equation?

[@danilsoncabral1991]

can i have access to this excel file of calculations please for studies

[@andrewscholes7953]

Thanks for this, really helped me for my uni project! I was wondering if you had a source for these calculations that I can include?

Hello Zeina Rahal, I have watch your video many times, and have learned a lot. I was able to recreate the spreadsheet file in LibreOffice Calc including the equations and regenerated the answers you got. I just have two questions. Is the "Cl/Cd vs. alpha Table" you used real or fictitious? I was trying to use the XFLR5 program to duplicated it with no success. My second question is, If the "Cl/Cd vs. alpha Table" you used is real, what is the source (book, website, software, etc.) of this table? Anyway, your video is very good, and I enjoyed it very much!

Is this procedure valid for the analysis of Vertical Axis Wind Turbine?
