How to create an "aerodynamic" form?

I've seen variations of this question asked a lot in the discussion forums (ie form finding through wind analysis), but I have yet to see an answer. At the simplest level, all I am really trying to do is use grasshopper to create an aerodynamic form.

The purpose of this aerodynamic form is to better channel wind towards a wind turbine. If possible, I would like to create an iterative process where I could see how different forms result in different wind speeds and directions.

I thought Kangaroo would be a good place to start, however, I cannot determine a decent method to achieve this. All I have currently figured out how to do is simulate wind forces against a mesh held down by anchor points.

Any suggestions for improving aerodynamics and/or channeling wind towards a particular point using grasshopper would be greatly appreciated!

You might want to check out the paper "Generative Fluid Dynamics: Integration of Fast Fluid Dynamics and Genetic Algorithms for wind loading optimization of a free form surface" by Angelos Chronis. It's available for free in the 2011 SimAUD proceedings.
