Since I'm new here, and I'm new with aerodynamics,
I am opening a new topic because I can't find something simular on the forum.
The whole problem is started by city regulations because they don't allow horizontal windmills.
So I started trying to calculate VAWT's. And I know something about programming... but not from Aerodynamics.
Problem: a flat plane, under an angle with the wind, moving in any possible angle.
I found the drag and lift formula, a formula to calculate Cd and Cl under different angles, so now I can calculate the force when it's standing stil.
But I need to know the force (and the power) when it's moving... in any direction.
I found several things about horizontal windmills, but I'm always getting stuck when I trie to reduce the formula from rotating to a flat plane with straight movement.
So it would help if someone could point me a direction 字串9
(formula, document...)
Greetings

thread1-231285: high AoA in xfoil is a question about VAWT too.
University of Reading I think it is did a bunch of work on VAWTs in the 80's & 90's. They built a couple of H configured units in Wales as I recall, worth a look? KENAT,
Have you reminded yourself of FAQ731-376: Eng-Tips.com Forum Policies recently, or taken a look at posting policies: http://eng-tips.com/market.cfm?
