What is it about?
A validated methodology that includes the stall-onset for vertical axis wind turbines motions into the Leishman-Beddoes model to predict the unsteady forces. The procedure is able to predict the power coefficient of any turbine with a different number of blades and considers accurately the pitch angle of the blades.

Why is it important?
Our findings show that considering the dynamic stall exclusive for vertical axis wind turbines into the Leishman-Beddoes model leads to a better prediction of the power coefficient of the turbines with any pitch angle and number of blades.
Perspectives
Trying to develop an algorithm that is fast to accurately predict the power coefficient of vertical axis wind turbines it made me realize how difficult is the aerodynamics in this device. Doing the research let me contact several scientific people around the world and I have seen the interest of the industry towards an optimal design of a wind turbine to use in urban areas.
