Airfoil and flat plate lift.

I'm trying to understand flat-plate lift well enough to 
model "bent flat plate" vertical axis wind turbines. While I 
started off thinking that these were a trivial or simplified 
version of a Savonius Rotor it appears that they are a 
combination lift and drag machine.

Simple to build. Not so simple to understand. One approach 
is "just build them and bend the 'blades' for best 
performance". Hopefully a modicum of theoretical 
appreciation will help at least a little.

Target application is an alternator driver.
