I wanna perform BEMT analysis on blades of different geometry and not just symmetric thin airfoil. How to do this?

One book I've used in the past is Martin O. L. Hansen's 'Aerodynamics of wind turbines'.

It covers extensively and step by step the beam element momentum theory. I've used it in the past to develop software for a wind energy project. The project used NACA airfoils, so you should be able to apply it to your work.

Last I remember I could find chapters or the whole thing available in public websites, so a quite search might yield some results.
