hello folks, I am in mechanical stream & am working on a project of VAWT of power 300 watt. I found a link where i can calculate power output for different parameter. Here's the link: http://usvawt.com/cgi/windpower.cgi where i took height as 2m and width as 3m. Now need to design airfoil blades. Guide me where to start from? Just know the concept of airfoil but don't know the design procedure. Thank you.
