Currently i am doing wind turbine blade optimization by coupling CFD solver and genetic algorithm . For 2D shape parmeterization, i have used PARSEC parmeterization and was able to generate airfoil shape and it works.
Now i want to extend my work in to 3D . Anyone who can give me a direction/references how i am going do it ? or how can i convert my 2D airfoil shape generated data in to 3D ?

Thanks !!

Aren't wind turbine blades just a loft between 2D sections? Getting a 3D geometry from a series of 2D sections defined along the span should be straight forward.

Most wind engineering books have good discussions on blade optimization in the context of blade element momentum theory. If you have a way to optimize your 2D profile then coupling that with a BEM solver to maximize your efficiency is pretty straight forward. Just be aware of the Betz limit and you should be fine.

Thanks for your reply.
Actually i have used direct forcing immersed boundary method for solver which is FVM based solver. i want some reference/guideline to develop code span wise surface to get 3D geometry from 2D section.

Thanks once again.
